If the provided connection does not have sufficient permission to read
"pg_stat_replication.state", and there is an entry for the node in
"pg_stat_replication", assume it's connected. Finer-grained detection
requires additional user permissions, nothing we can do about that.
Previously the check verifying that a node has connected to its upstream
merely assumed the presence of a record in pg_stat_replication indicates
a successful replication connection. However the record may contain a
state other than "streaming", typically "startup" (which will occur when
a node has diverged from its upstream and will therefore never
transition to "streaming"), which needs to be taken into account when
considering the state of the replication connection to avoid false
positives.
Add notes to the documention mentioning that after postgres or repmgr
upgrades (postgres major upgrades), there are some changes that need
to be taken care of.

Previously these actions were hard-wired to assume node IDs would only
ever have two digits at most.
Refactor to use the same table generation code as other actions, which
properly handles variable column sizes.
The option was never actually set anywhere.
By removing it, readline will now produce a reasoanably helpful message
in the offchance it is provided, e.g.:
option '--node=foo' is ambiguous; possibilities: '--node-id' '--node-name'
repmgr creates a file with a list of tablespace files to fetch from
Barman, however the file may not actually have been flushed to disk
at the point the rsync operation was executed, so may be incomplete
or empty.
Also fix handling of tablespace remapping.
Addresses GitHub #650.
If the primary connection went away, and the upstream is not the
primary, attempt to reconnect if the monitoring update fails.
If the upstream is the primary, the reconnection will happen on
the next connection check.
This expunges two large and cumbersome sets of if/else statements and
the T_CONFIGURATION_OPTIONS_INITIALIZER macro, all of which needed to
be kept in sync when adding/modifying configuration file parameters.
