AAP-39220 : Run ccspv2 build_report outside awx

[himdel]

Issue: AAP-39220
Follows #45

Make it possible to run the CCSPv2 build_report phase outside of the AWX environment.

Previously, when importing from awx failed, the util would try $AWX_PATH or /awx_devel, and fail when that failed.
Now, it will warn, but fall back to a mock_awx implementation.

Adds django-ansible-base as a dependency for the standalone mode,
imports advisory_lock from ansible-base when present (standalone or 2.5), or from awx otherwise (2.4).
(Either replaces #47, or replace this bit with #47.)

Mocks:

• awx.prepare_env - sets up DJANGO_SETTINGS_MODULE to point at mock_awx/settings
• awx.main.get_awx_version - hardcoded to 24.6.123 for now
• awx.main.get_awx_http_client_headers - license info hardcoded to UNLICENSED
• awx.main.datetime_hook - small wrapper around django parse_datetime, copied
• (settings - empty module)

(The idea is to hardcode these for testing, and later replace with a param or an os.environ.get when we need to.)

This does not do anything about anything missing for the gather phase of ccspv2, or any other reports or backends - still unaddressed:

• Job
• Setting
• access_registry
• get_license
• (and gather, renewal, s3, crc...)

Testing:

cd metrics-utility
gh pr checkout 51 # OR git fetch upstream pull/51/head ; git checkout FETCH_HEAD

./run-ccsp2-build
# check metrics_utility/test/test_data/reports/2024/04/CCSPv2-2024-04.xlsx

(The run-ccsp2-build script is just a convenience wrapper .. maybe we should move it to a tools dir or some such, ideas?)

(Possibly there should be an explicit param to allow running with the mocked env if we wanted to preserve 100% error compatibility too - but that means parsing the options before calling into ManagementUtility which deals with options and doesn't really align with the end goal?)

(Mocking awx is to help unblock testing, adding relative import dirs may not work so well for RPM installs.)
