Add a new keepalive config: mqtt.keepalive_check_interval(default is 30s)
The time interval to check for mqtt packets.
range is [1s, Interval(in connect packet) div 2 s].
So the time to determine if a timeout is needed is:
min: interval * multiplier
max: interval multiplier + 1 check_interval
eg:
interval = 60s, multiplier = 1.5, check_interval = 30s
should be keepalive_timeout between 90s(60*1.5) and 120s(60*1.5+30)
If the user expects to reduce this section. You can reduce the factor:
interval = 60s, multiplier = 1.5, check_interval = 10s
should be keepalive_timeout between 90s(60 * 1.5) and 100s(60 * 1.5+10)
Release version: v/e5.7.2
