If LCP keepalive mechanism is enabled in menuconfig, it's statically configured on creation of an interface and cannot be changed runtime. In some cases it's useful to relax LCP criteria during runtime operation, for example before initiating OTA. This config option allows for disabling already enabled LCP echo (this setting becomes effective after reconnecting, i.e. initializing a new session) Closes https://github.com/espressif/esp-protocols/issues/287
