Support to cleanup disk cache when enabled

[kashishmittal55]

Add a helper method to cleanup the local disk cache such that teardown can be handled correctly
Also do this automatically when the context exit occur.

This change will also enable the cleanup=True for local disk cache as that will be the right thing to do most of the times.
