Use PSRAM for MQTT publishing and make it scheduled (#2113)

* Run the Homeassistant Discovery directly after connecting to the broker. Before it was delayed 10s and happened while the first round alredy was in progress

* schedule sending HA discovery and static topics

* Allow setting QOS for MQTT topics

* .

* .

* change MQTT QOS1 expiration time from (default) 30 to 5s

* add logging of heap change on MQTT topic sendings

* wait for MQTT transmission timeout after publishing

* use QOS0 for Homeassistant Discovery topics. the messages then could possibly get lost but we save a lot of heap

* .

* use PSRAM for the MQTT outbox

* use QOS1 for HA discovery again

* .

* .

* disable delay, not needed with PSRAM

* .

* consolidated scheduledSendingOf_DiscoveryAndStaticTopics into sendingOf_DiscoveryAndStaticTopics_scheduled

* Send Homeasstsiatnt Discovery and static data in MQTT step instead of when the wifi gets connected

* "WIFI roaming" by channel scan (AP switching at low RSSI) (#2120)

* Activate 802.11kv wifi mesh roaming

* Activate roaming by scanning

* Revert stack reducation

* move Wifi, LWIP and BSSI to PSRAm

* added State Class "measurement" to rate_per_time_unit (#2116)
