CHE-6114: Fix problems with project explorer performance in big projects

[vinokurig]

What does this PR do?

1. Add ability to get Git status with filter.
2. Reworked Injecting VCS status info in Project service to make Status request only once instead of requesting each time in the loop.
3. Removed format parameter from get status method in Git Service, because it is redundant and do not affects to anything, since we use Jgit as a Git engine.

The main goal of calling git status with filter is to increase performance. Git status request without filter might be slow if project contains a lot of files.
