641b1b249e Attempt to reconnect to MySQL 
For MaterializeMySQL databases, attempt to reconnect if the connection
to MySQL is lost.  The existing setting
`max_wait_time_when_mysql_unavailable` is used to control how often we
attempt to reconnect.  This setting can now be set to a negative value
to disable reconnects.

11c9c8cb10 Reset sequence number on disconnect 
Reestablishing the connection for an existing MySQLClient object would
never work because the sequence number would be wrong on the new
connection.

8e95d6e174 Add method to metadata class to start replication 
Previously this was done by the constructor.  This makes it
possible to restart replication with an existing metadata object.

e6711675a1 Make handling of unavailable MySQL consistent 
If MySQL was unavailable when loading an existing database on startup,
we would previously load the database, fail to start synchronization,
but allow queries to the database.  Change this to only allow queries
if the `allows_queries_when_mysql_lost` setting is on, so that the
behavior is consistent with what happens if the connection to MySQL is
lost while ClickHouse is running.

Also retry connection to MySQL if MySQL is unavailable when ClickHouse
is started (we would previously reconnect only if the connection was
lost during the initial dump of existing data).
