If the node is bootstrapped with auto_boostrap disabled, it will not
wait for schema sync before creating global keyspaces for auth and
tracing. When such schema changes are then reconciled with schema on
other nodes, they may overwrite changes made by the user before the
node was started, because they will have higher timestamp.
To prevent that, let's use minimum timestamp so that default schema
always looses with manual modifications. This is what Cassandra does.
Fixes#2129.
data_resource lookup uses data_resource::name(), which uses sprint(), which
uses (indirectly) locale, which takes a global lock. This is a bottleneck
on large machines.
Fix by not using name() during lookup.
Fixes#1419

In initial implementation I figured this was not required, but
we get issues communicating across nodes if system tables
don't have the same UUID, since creation is forcefully local, yet
shared.
Just do a manual re-create of the scema with a name UUID, and
use migration manager directly.

Only difference from previous sleep is that we will
explicitly delete the objects if the process terminates
before tasks are run. I.e. make ASas happier.

User db storage + login/pwd db using system tables.
Authenticator object is a global shard-shared singleton, assumed
to be completely immutable, thus safe.
Actual login authentication is done via locally created stateful object
(sasl challenge), that queries db.
Uses "crypt_r" for password hashing, vs. origins use of bcrypt.
Main reason is that bcrypt does not exist as any consistent package
that can be consumed, so to guarantee full compatibility we'd have
to include the source. Not hard, but at least initially more work than
worth.
