Add ability for Bitbucket clients to specify repos by projectKey
Created by: susantoscott
Previously Bitbucket clients could only specify repos by projectName. Now, if projectKeys are specified in s.config.ProjectKeys, then those repos would be returned as well.
Test plan
go test -run TestBitbucketServerSource_ListRepos -- to list all repos go test -run TestBitbucketServerSource_ListByRepos only -- to list repos in the config go test -run TestBitbucketServerSource_ListByRepositoryQueryDefault -- to list repos by projectName go test -run TestBitbucketServerSource_ListByRepositoryQueryAll -- using all as the query go test -run TestBitbucketServerSource_ListByRepositoryQueryNone -- using none as the query go test -run TestBitbucketServerSource_ListByProjectKey -- to list repos by projectKey
