Running check datascale can create large history of keyspaces and
internal fragmentation. Allow user to run auto compact and defrag
when run check datascale.
Create a new command similar to check perf that can check the memory
consumption for putting different workloads on a given endpoint. If no endpoint
is provided, localhost will be used. Return user with a message that whether
there are enough memory for a given workload with pass or fail.
