scheduler: allow to configure userids for which the scheduler should

not scan the host table. This was previously hardcoded for
  Einstein@home to prevent some users with many (identical) hosts
  from flooding the DB with slow queries. Now add
  <dont_search_host_for_userid>userid</dont_search_host_for_userid>
  to the project config (in config.xml) for each such userid.
