dspace_statistics_api/indexer.py: Query multiple shards
...
DSpace's stats-util script splits the Solr statistics core into yearly
shards. We need to use Solr's `shards` query parameter in order to get
the statistics for previous years. This commit adds a helper function
to enumerate the active Solr cores to find yearly shards matching the
statistics-YYYY pattern and add them to the query.

Refactor database code to use a context manager
...
Instead of opening one global persistent database connection when
the application I am now abstracting it to a class that I can use
in combination with Python's "with" context. Both connections and
cursors are kept for the context of each "with" block and closed
automatically when exiting.

Correct issues highlighted by Flake8
...
Flake8 validates code style against PEP 8 in order to encourage the
writing of idiomatic Python. For reference, I am currently ignoring
errors about line length (E501) because I feel it makes code harder
to read.
This is the invocation I am using:
$ flake8 --ignore E501 dspace_statistics_api

Add basic API documentation on root (/)
...
I had imagined plugging in an interactive Swagger or OpenAPI instance
here, but that's actually much more involved in Falcon than I want to
deal with right now.

dspace_statistics_api/app.py: remove unused code

This was added accidentally when I refactored. I was trying to see
if I could use Falcon's on_exit() hook.

Add "application" alias to API object
...
By default gunicorn looks for an "application" object to run, so this
saves us having to type api:app.

Refactor project structure

This follows guidance from several well-known Python best practices
guides. Basically, the idea is create a package for the application
that is comprised of several re-usable modules.
