Mark experimental smartmach feature as enabled to suppress warnings in perl 5.18+.
This doesn't mitigate the fact that smartmatch is now considered experimental,
but use of smartmatch in this script is limited to simple given/when with string literals.

Add an initial state to cluster hash, this way we can tell the difference between a cluster that has no suitable target nodes and where the previous cluster state has not yet been initialized.
We also want to register that things have changed and there is now no suitable node, that way we can write nothing and effectively shut off the pool.

Changes:
- Ensure we always read Slony configuration from the origin node when possible
- Add max_ro_lag=<n> seconds parameter to allow forced reconfiguration of read-only pools when subscribers start to lag

A couple of minor changes:
- Added extra configuration parameter 'only_follow_origins' to only repoint pgbouncer configuration if the origin of the monitored sets changes, which is what we usually want.
- Only write cluster status information file when cluster status has actually changed.
