No way to configure connection retries and timeouts through the charm

[Tiago Pasqualini da Silva]

octavia-charm does not expose the configuration for timeouts and number of retries when trying to reach an amphora[1]. The default value is huge, which makes the failover process take a really long time when both amphorae are lost (up to 1 hour). Making those values configurable would make it possible for admins to tune that for their specific cloud needs.
