Describe the bug

It currently seems to be impossible to add a new public key to user's account using GHMyself. POST /user/keys is the relevant GitHub API endpoint.

To Reproduce
Read docs on GHMyself and observe the method not being present

Expected behavior
`GHMyself::addK

I would like a PR to be rebuilt if its target branch is updated.

Use case:

• PR 1 is opened to develop;
• PR 2 is opened to develop;
• Jenkins notices and tests both.
• PR 1 is accepted, breaks the build when PR2 is merged to develop;
• Jenkins notices the merge on develop, re-tests PR2 and detects the failure.

It seems that the [bitbucket pluging](https://github.com/nishio-dens/bitbuck

RtReleaseAssets upload use a static uri uri: "https://uploads.github.com"
this.request.uri().set(URI.create("https://uploads.github.com"))

It should leverage the upload_url in the repository github response.
