Changes in DRS queries

Changes in DRS queries in Plugin 01 and 17 to make avoid running the
same query multiple times.
Added Storage DRS output to Plugin 17.
Removed needing to set $DRSMigrateAge from Plugin 17 which is no longer
necessary and was potentially confusing as it appeared twice during
./vCheck.ps1 -config
Merge pull request #3 from jonathanmedd/master
