Add a failover option to subscriptions.
This commit introduces a new subscription option named 'failover', which
provides users with the ability to set the failover property of the
replication slot on the publisher when creating or altering a
subscription.
This uses the replication commands introduced by commit 7329240437 to
enable the failover option for a logical replication slot.
If the failover option is set to true, the associated replication slots
(i.e. the main slot and the table sync slots) in the upstream database are
enabled to be synchronized to the standbys. Note that the capability to
sync the replication slots will be added in subsequent commits.
Thanks to Masahiko Sawada for the design inputs.
