Allow database client to notice schema changes about kcidb

can i have a try at this @spbnick

Sure! You've actually implemented one step towards this already - storing the "database" string in the client (even though that is still to be merged).

can the interphase be something like this @spbnick
def refresh(self):
"""
refresh recreates the client on request
:return:
"""
return Client(self.database)

Yeah, something like that. Only perhaps call it reset, as it would basically amount to discarding the existing driver instance behind the client, and creating a new one using the same "database" string, not actually "refreshing" some data from somewhere, in the sense of e.g. a browser page refresh. We do refresh the information on which schema the database is using, but to do that we destroy and recreate the driver. I.e. we would reset in order to do a refresh, so let's call it what it is: reset.
