Fixes https://emqx.atlassian.net/browse/EMQX-9864
Setting a very large interval can cause `erlang:start_timer` to crash.
Also, setting auto_restart_interval or health_check_interval to "0s"
causes the state machine to be in loop as time 0 is handled separately:
| state_timeout() = timeout() | integer()
| (...)
| If Time is relative and 0 no timer is actually started, instead the the
| time-out event is enqueued to ensure that it gets processed before any
| not yet received external event.
from "https://www.erlang.org/doc/man/gen_statem.html#type-state_timeout"
Therefore, both fields are now validated against the range [1ms, 1h],
which doesn't cause above issues.
