tests: add global test_context_fixture
Move the existing app_test_context_fixture from test_pullrequests.py to
conftest.py to make it available to all test modules.
It is useful in two cases:
1. there is test setup code (xUnit style) that needs to execute in the same
test context as the actual test.
2. even without test setup code, an entire test needs to be executed in a
test context. In this case, the fixture just reduces code complexity by not
requiring changes in the test code (compared to standard 'with
test_context').
It is possible to apply this (or any) fixture to an entire test class using
the class decorator
@pytest.mark.usefixtures("...")
This is similar to 'autouse=True' but can be used even if the fixture is
defined elsewhere.

usage: $0 CONFIG_FILE FROM_REV [TO_REV]
Runs a database migration from FROM_REV to TO_REV (default: current
working directory parent), using the specified CONFIG_FILE (.ini file).
Test is run using a clean Kallithea install, in a temporary virtual
environment. FROM_REV and (optional) TO_REV should be Mercurial revision
identifiers (e.g. changeset hash or a version number tag). The working
directory is not touched, but the database referenced in the config file
will be (re)created.
Only SQLite is available out of the box; for MySQL or PostgreSQL, set
the EXTRA environment variable to the required package(s), and it'll
be installed in the virtual environment. (E.g. EXTRA=MySQL-python or
EXTRA=psycopg2.)
The temporary directory is not removed, allowing follow-up examination
of the upgrade results. It is, however, created in /tmp by default,
which many Linux distributions automatically clean at regular intervals.
