Add a new endpoint to filter build metadata

[Arafo]

Hi!

I would love the ability to filter build metadata by key / value

For example: Build 1 metadata [ "git_commit_sha": "build_1_sha.", "git_branch": "a_git_branch" "key_x": "another_value" ... ]

Build 2 metadata [ "git_commit_sha": "build_2_sha", "git_branch": "a_git_branch" "key_x": "another_value" ... ]

By being able to filter metadata by git_branch for example, I'd be able to get additional metadata fields from other builds which could help to analyze possible improvements or regressions.

Happy to propose an implementation if this is a welcomed addition.

Thanks!
