[Feature Request] support requiring "signed commits" on `github_branch_protection`

Affected Resource(s)

Please list the resources as a list, for example:

• github_branch_protection

Important Factoids

Some organizations require commits to be signed to verify identity of submitter for legal reasons.

It is available in the rest api: https://developer.github.com/v3/repos/branches/#add-required-signatures-of-protected-branch but I do not see it yet in the upstream go library: https://github.com/google/go-github/blob/v15.0.0/github/repos.go so we are blocked until it is added. I have created google/go-github#902 upstream to track.

[majormoses]

The functionality has been merged upstream into master but has not been released yet.
