Grant alert bot reporter access programmatically

See merge request gitlab-org/gitlab-ee!14801

Before this commit the alert bot could not create labels on project
with private issue access ALTHOUGH it has `:reporter_access`.

Reason: In order to check project `issues_disabled` rule we check user's
team access level. AFAIK, there's no way to utilize `:reporter_access`.

Allows the client class to accept a project with commits,
branches, and merge requests and then serializes these
to the JSON format Jira expects
