feat: added capability to import custom data files

[lanathlor]

Changes Proposed:

This PR proposes changes to:

• Core (units, players, creatures, game systems).
• Scripts (bosses, spell scripts, creature scripts).
• Database (SAI, creatures, etc).

Issues Addressed:

I found no easy way to inject custom .dbc file in worldserver container on a running server. This change add a container using rsync to merge custom data files with existing ones.

SOURCE:

The changes have been validated through:

• Live research (checked on live servers, e.g Classic WotLK, Retail, etc.)
• Sniffs (remember to share them with the open source community!)
• Video evidence, knowledge databases or other public sources (e.g forums, Wowhead, etc.)
• The changes promoted by this pull request come partially or entirely from another project (cherry-pick). Cherry-picks must be committed using the proper --author tag in order to be accepted, thus crediting the original authors, unless otherwise unable to be found

How to Test AzerothCore PRs

When a PR is ready to be tested, it will be marked as [WAITING TO BE TESTED].

You can help by testing PRs and writing your feedback here on the PR's page on GitHub. Follow the instructions here:

REMEMBER: when testing a PR that changes something generic (i.e. a part of code that handles more than one specific thing), the tester should not only check that the PR does its job (e.g. fixing spell XXX) but especially check that the PR does not cause any regression (i.e. introducing new bugs).

For example: if a PR fixes spell X by changing a part of code that handles spells X, Y, and Z, we should not only test X, but we should test Y and Z as well.

Hey, thanks for your pull request.

Unfortunately, I'm not sure that we can accept this pull request, as custom data isn't something directly supported by the project. The configurations for the Dockerfile and the compose file target a "standard" deploy of AzerothCore, with the most custom changes being AzerothCore modules. I recommend moving your changes to a docker compose override file, and then committing that file to a fork of this repo.

I'd be happy to defer to the input of other AzerothCore maintainers, but I think this PR is safe to close out.

Thank you for understanding.
