Support using git addon version in makefile manage

[MustafaJafar]

Changelog Description

An alternative to #94

This PR adds support for AYON_USE_GIT_SUFFIX_FOR_ADDONS env var for initializing the processor services with addon version with the +git suffix. This is the same env var used on the ayon-docker server.

AYON_SERVER_URL=http://localhost:5000/
AYON_API_KEY=veryinsecureapikey
AYON_USE_GIT_SUFFIX_FOR_ADDONS=True

Additional details

when working with kitsu addon development, it's possible to develop from within the ayon-docker directly or from a separate directory.

Although, developing from within the ayon-docker/addons directly, if someone does, running servies live from source code won't work becasue the service is not initialized to work with the +git vesion. so, it fails to fetch settings.

I think such a solution can be adapted in other addons with services.

Testing notes:

1. when setting AYON_USE_GIT_SUFFIX_FOR_ADDONS to true it should set the addon version to +git.
2. when no setting it or setting it to false, the actual addon version should be used.
