Description

Related to CASSANDRA-8296, we should add a check of the system wall clock at startup to make sure it 'looks' reasonable. This check will prevent a node from starting with a bad generation in it's gossip metadata (and causing many problems downstream of that).

Note that this is intended as a simple check of the clock at startup and not a comprehensive, ongoing check of clocks during the running of the process.
