Authorize Git LFS HTTP requests

According to [1] Git LFS client uses HTTP Basic Auth to authorize
requests. Change adds logic to verify that the user has permission to
perform requested operation.

Notes:
1. in order to authorize requests
  auth.gitBasicAuth = true
needs to be set in gerrit.config.
2. SSH Auth gets broken with this change. It will be fixed in the follow
up change.
