Changing LPMODE timing is different between cables.
We want to add functionality to make sure LPMODE has changed.
For that, the wait_until utility is used and every 1 second (until timeout), it will check with lower-layers what is the current Lpmode.
Once it is the expected mode, set_lpmode() functino will return True.
If after seconds, Lpmode is still not in the expected mode, set_lpmode() function will return False.
- How I did it
Add use of wait_until function to make sure lpmode was changed.

The creation of system EEPROM VPD file "/var/run/hw-management/eeprom/vpd_info" is triggered by the udev event during the system boot up, in case the CPU is busy during the bootup, the udev event handling can be delayed, and need to wait for some more time for the file creation.

Fix the code to work also after warm reboot to work with FW controlled ports.
In warm reboot the control state sysfs of each port does not change unlike reboot or fast boot.
- How I did it
1. Check procfs cmdline if warm reboot done this is due to the fact pmon don't recognize warm reboot when it's taking place since pmon is loaded after warm reboot is finished.
2. If warm reboot done, check in static detection part for each port if it's FW controlled. If so, leave it this way and stop the state machine flow (set it to final state).
- How to verify it
1. Boot a switch with CMIS host management with at least one FW controlled port (non active cables or non cmis cables) then run warm reboot.
2. Verify no errors of sysfs reading appears for control sysfs
- Why I did it
If a PSU is not present, there could be error log while restarting psud or thermalctld:

Jan 8 17:15:57.747723 sonic ERR pmon#thermalctld: Thermal sysfs /run/hw-management/thermal/psu2_temp1 does not exist

if a PSU is not present, we should not check the PSU temperature sysfs.

* move seek to beginning of sysfs fd before reading to resolve power_good

2. sfp should get temperature threshold from EEPROM because SDK sysfs is not yet supported

new thread in a new file and changing logic in platform code in chassis.py which is calling this thread from get_change_event()
this thread in the new file handles the state machine per port.
first the static detection takes place once the thread is up (during switch bootup sequence), until final decision if it's FW control or SW control module.
After it ends, the dynamic detection takes place, listening to changes in the sysfs fds, per port,
so it will be able to detect plug in or out events of a cable.

In order to activate FW after it was upgraded need to perform reboot.
If reboot wasn't performed and user need to upgrade to another SONiC image then it will fail.
The reason for that is that during SONiC upgrade new FW should be installed but it will fail because previously installed FW wasn't activated.
In order to allow 2nd FW upgrade without reboot in-between need to reactivate FW image.
This change handles such flow.
Example of issue scenario:
User installed SONiC image on the switch
Then for some reason FW was upgraded by user or script but reboot was not performed to activate it.
After that upgrade to new SONiC image will fail because new image need to install FW but it fails due to previous one wasn't activated.
- How I did it
In "mlnx-fw-upgrade" script check if FW upgrade failed with the error that FW was already installed but reboot was not performed.
If so then perform FW image reactivation and try to upgrade FW again.
- How to verify it
Install SONiC image on the switch
Then upgrade FW but don't perform reboot.
After that upgrade to new SONiC image and check that upgrade was successfull.

SONiC service determine-reboot-cause might run before driver creating reset cause files. In that case, the reset cause will be "Unknown". This PR introduces a wait mechanism to wait for reset cause sysfs files ready.

watchdogutil uses platform API watchdog instance to control/query watchdog status. In Nvidia watchdog status, it caches "armed" status in a object member "WatchdogImplBase.armed". This is not working for CLI infrastructure because each CLI will create a new watchdog instance, the status cached in previous instance will totally lose. Consider following commands:
admin@sonic:~$ sudo watchdogutil arm -s 100 =====> watchdog instance1, armed=True
Watchdog armed for 100 seconds
admin@sonic:~$ sudo watchdogutil status ======> watchdog instance2, armed=False
Status: Unarmed
