Reduce the number of queues fetched in fetchMountInfo

Each tape drive is tied to a single logical library. Therefore there is no need to fetch all queues in OStoreDB::fetchMountInfo(...).
We should simply fetch the queues that are associated with the logical library (filter either by tape VID or tape pool name).

TODO:

• Pass logicalLibraryName down to OStoreDB::fetchMountInfo(...).
• Inside OStoreDB::fetchMountInfo(...) call two new functions:
  • Names:
    • m_catalogue.getCachedTapes(const TapeSearchCriteria &searchCriteria);
    • m_catalogue.getCachedTapePool(const TapeSearchCriteria &searchCriteria);
  • Use the logicalLibraryName as a search criteria.
  • Cache the results:
    • The values are not expected to change frequently and we can tolerate inconsistencies for a while...
• Use the list of tapes/tape-pools to avoid fetching unnecessary queues from the object store DB.
• Remove the parameter logicalLibraryName from Scheduler::sortAndGetTapesForMountInfo(...):
  • With the new logic, this parameter becomes redundant. In addition, we avoid an unnecessary query to the catalogue DB.
