Add Support for More R2DBC Pool Metrics

See original GitHub issue

The R2DBC connection pool metrics exposed by Actuator are currently very limited, we only get a few gauges about the current pool status as exposed by io.r2dbc.pool.PoolMetrics. Other important metrics like number and latency of connection acquire/allocation operations are missing.

I looked through the R2DBC ConnectionPool source code and found that the ConnectionFactory.Builder has a method to accept a reactor.pool.PoolMetricsRecorder, which can be used to track those metrics.

Would you consider integrating this with Actuator? It looks like it should be pretty straight-forward to implement a PoolMetricsRecorder that uses Micrometer’s MeterRegistry to track those metrics.

Thanks, @simonbasle. I think it would be good for @shakuzen, @jonatan-ivanov, @marcingrzejszczak to cast an expert eye over this.
