示例1: runRegisteredPluginsCrawl
/**
* Runs registered plugins' crawl function.
*
* About crawler exclusivity (mutex usage):
* When launched by an admin, no other user, admin or not, will be able to launch a crawl until this one is done.
* When launched by a non-admin, we first check that no admin run is under way, and if that's the case,
* we launch a crawl for the current user only.
* No user will be able to launch two crawls in parallel, but different non-admin users crawls can run in parallel.
* @throws UnauthorizedUserException If user is not logged in
* @throws CrawlerLockedException If a crawl is already in progress
* @throws InstallerException If ThinkUp is in the midst of a database upgrade
