Rename items.py to stats.py
It is no longer used only for item-related statistics functions.

Add communities and collections support to API
The basic logic is similar to items, where you can request single
item statistics with a UUID, all item statistics, and item statis-
tics for a list of items (optionally with a date range). Most of
the item code was re-purposed to work on "elements", which can be
items, communities, or collections depending on the request, with
the use of Falcon's `before` hooks to set the statistics scope so
we know how to behave for the current request.

Other than the minor difference in facet fields, another issue I
had with communities and collections is that the owningComm and
owningColl fields are multi-valued (unlike items' id field). This
means that, when you facet the results of your query, Solr returns
ids that seem unrelated, but are actually present in the field, so
I had to make sure I checked all returned ids to see if they were
in the user's POSTed elements list.

TODO:
  - Add tests
  - Revise docstrings
  - Refactor items.py as it is now generic

20c8ba0cf8 indexer.py: Add support for communities and collections
The logic to get views and downloads is very similar to that used
for items, but we facet by different fields. This uses a generic
function for indexing that takes an "indexType" and a "facetField"
parameter. The indexType parameter controls which database table
to insert into, and the facetField parameter indicates which field
to facet by in Solr.

Move all imports to top of file
A few months ago I had an issue setting up mocking because I was
trying to be clever importing these libraries only when I needed
them rather than at the global scope. Someone pointed out to me
that if the imports are at the top of the file Falcon will load
them once when the WSGI server starts, whereas if they are in the
on_get() or on_post() they will load for every request! Also, it
seems that PEP8 recommends keeping imports at the top of the file
anyways, so I will just do that.

Imports sorted with isort.

See: https://www.python.org/dev/peps/pep-0008/#imports

dspace_statistics_api/indexer.py: Use fl parameter
When indexing item views and downloads the only field we need is the
the id. The `fl` parameter tells Solr which fields to return in the
search results. This should theoretically be more efficient, though
I don't have any time to figure out how to measure it right now.

dspace_statistics_api/indexer.py: Use -isBot:true
Minor change to bot filtering. We should use a negated match for

important).

dspace_statistics_api/items.py: Move util import
Move util import from global scope because it causes tests to fail.
We don't need the set up the Solr connection unless we're actually

running the API in production or during tests where the connection
has been set up.

dspace_statistics_api/app.py: Refactor for testability
I thought it was clever to only import these in the on_post handler
because they aren't needed elsewhere, but it turns out that this is
not a common pattern and even causes problems with testability.

First, if the imports are at the top of the file as PEP8 recommends,
then the WSGI server will import them once when it loads the app and
they remain in memory for the lifecycle of the app. If the imports
are in the on_post handler they would be re-imported on every request!

Second, this pattern of importing in a method makes it tricky to use
object patching in mocks.

Refactor /items POST handler to use a before hook
This allows us to do the dirty work of parsing, validating, and
setting local variables from the POST parameters outside of the
on_post function. We then share the parameters via the req.context
object. Functionally it is the same, but readability is better
and it's a neat trick that I could use elsewhere.

dspace_statistics_api/items.py: Fix flake8 warning
According to flake8 we need to use a different syntax for strings
with backslash escape sequences:

> As of Python 3.6, a backslash-character pair that is not a valid
> escape sequence now generates a DeprecationWarning. This will
> eventually become a SyntaxError.

The warning was:

    W605 invalid escape sequence '\-'

dspace_statistics_api/app.py: Use bounded_stream in on_post
For reasons I don't quite understand, we need to use bounded_stream
in the on_post request handler in order to use simulate_post() with
the testing client in Falcon 2.0.0. Normal runtime operation via
gunicorn does not have any issues with stream.

dspace_statistics_api/indexer.py: Update comment
I don't remember why we needed the stats, but it seems that it was
because without them there is no way to know how many results were
returned and therefore no way to know how many pages we'll need to
iterate over. Having the total number allows us to use a limit and
and offset to page through them deterministically.

dspace_statistics_api: Add support for date ranges to /items
You can now POST a JSON request to /items with a list of items and
a date range. This allows the possibility to get view and download
statistics for arbitrary items and arbitrary date ranges.

The JSON request should be in the following format:

    {
        "limit": 100,
        "page": 0,
        "dateFrom": "2020-01-01T00:00:00Z",
        "dateTo": "2020-09-09T00:00:00Z",
        "items": [
            "f44cf173-2344-4eb2-8f00-ee55df32c76f",
            "2324aa41-e9de-4a2b-bc36-16241464683e",
            "8542f9da-9ce1-4614-abf4-f2e3fdb4b305",
            "0fe573e7-042a-4240-a4d9-753b61233908"
        ]
    }

The limit, page, and date parameters are all optional. By default
it will use a limit of 100, page 0, and [* TO *] Solr date range.

now the black formatter requires Python 3.6 and all our systems are

5955868b9a dspace_statistics_api/app.py: Use UUID
DSpace 6+ uses a UUID for item identifiers instead of an integer so
we need to adapt our PostgreSQL queries to use those. Note that we
can no longer sort results in the "all items" endpoint by ID. Also,
we need to use parameterized psycopg2 queries instead of strings to
support queries with UUIDs properly. To use the Python UUID objects
elsewhere in the code we need to make sure that we cast them to str.

hing there.
