Changing the strategy on this. Nova is a good example here -- it uses regular expressions for sqlite, mysql or postgres databases, and uses LIKE as a fallback for other databases.

For the Sahara case, we officially support mysql or postgres, We can use regular expressions for those two dbs, and provide only exact matching for anything else.

regular expressions will be enabled for a subset of columns on sahara objects -- things like name, description, etc. Thinks like uuid fields will not support it.
