Nadav Har'El 5895dff03b migration_manager: unique timeout exception for wait_for_schema_agreement() ...

Before this patch, if wait_for_schema_agreement() times out, it threw
a generic std::runtime_error, making it inconvenient for callers to
catch this error only. So in this patch we create and use a new exception
type, schema_agreement_timeout, based on seastar::timed_out_error.

Although wait_for_schema_agreement() was added in commit
a429018a8a was a utility function used in
a dozen places, it has become less interesting after we introduced schema
changes over Raft, and over the years most of the callers to this function
were removed, except one in view.cc which uses an infinite timeout, so
doesn't care about the timeout exception type.

In the next patch we want to add a new caller which *does* care about
the time exception type - hence this patch.
