feat(repodb): add user related information to repodb (#1317)

Initial code was contributed by Bogdan BIVOLARU <104334+bogdanbiv@users.noreply.github.com>
Moved implementation from a separate db to repodb by Andrei Aaron <aaaron@luxoft.com>

Not done yet:
- run/test dynamodb implementation, only boltdb was tested
- add additional coverage for existing functionality
- add web-based APIs to toggle the stars/bookmarks on/off

Initially graphql mutation was discussed for the missing API but
we decided REST endpoints would be better suited for configuration



feat(userdb): complete functionality for userdb integration

- dynamodb rollback changes to user starred repos in case increasing the total star count fails
- dynamodb increment/decrement repostars in repometa when user stars/unstars a repo
- dynamodb check anonymous user permissions are working as intendend
- common test handle anonymous users
- RepoMeta2RepoSummary set IsStarred and IsBookmarked



feat(userdb): rest api calls for toggling stars/bookmarks on/off



test(userdb): blackbox tests



test(userdb): move preferences tests in a different file with specific build tags



feat(repodb): add is-starred and is-bookmarked fields to repo-meta

- removed duplicated logic for determining if a repo is starred/bookmarked
