feat: make healthcheck more resilient (retry + reconnect)

[Dentrax]

In current implementation, I noticed healthcheck function ^1 does not support for retrying along with graceful handling. ^2

Proposal It would be nice to add a something failureThreshold to ConfigHealthCheck. So that after ping fails failureThreshold times in a row, go-dcp-client should treats the CB connection as unhealthy and triggers a restart/reconnect for that specific server.

Happy to discuss reasonable.
