Egon Elbre 76fdb5d863 storage: add configurable lookup limits
Currently storage tests were tied to the default lookup limit.
By increasing the limits, the tests will take longer and sometimes
cause a large number of goroutines to be started.

This change adds configurable lookup limit to all storage backends.

Also remove boltdb.NewShared, since it's not used any more.
