User Id string support

[brenwell]

Hey there. First up what a great provider!

I have a small issue I would like to solve but I am struggling a little as I am a TF noob. The user_id used in the default reviewers resource is expecting an int however my bitbucket server instance is using the username for the id, which is obviously a string. I would love to help fix this, but I would need a small push in the right direction. I presume it needs to support both and I am not quite sure how to do that. Any help is appreciated. Thanks

After some further research, I think this issue is a result of something unusual in our Bitbucket server setup.
