[SYS] Improve central queue stability (#1796)

* [SYS] Improve central queue stability

Improve central queue stability and add metrics

* Change partition for esp32dev-pilight-somfy-cc1101

to avoid program size too big error message with esp32dev-pilight-somfy-cc1101

* Only check for gateway updates at the start

to avoid consuming extra memory during operations
