Port of https://github.com/emqx/emqx/pull/10154 for `release-50` Fixes https://emqx.atlassian.net/browse/EMQX-9099 Originally, the `resume_interval`, which is what defines how often a buffer worker will attempt to retry its inflight window, was set to the same as the `health_check_interval`. This had the problem that, with default values, `health_check_interval = request_timeout`. This meant that, if a buffer worker with those configs were ever blocked, all requests would have timed out by the time it retried them. Here we change the default `resume_interval` to a reasonable value dependent on `health_check_interval` and `request_timeout`, and also expose that as a hidden parameter for fine tuning if necessary.

Change the default resume_interval for bridges and connectors to be
the minimum of health_check_interval and request_timeout / 3.
Also exposes it as a hidden configuration to allow fine tuning.
Before this change, the default values for resume_interval meant
that, if a buffer ever got blocked due to resource errors or high
message volumes, then, by the time the buffer would try to resume its
normal operations, almost all requests would have timed out.
