* [BFN] Fix for run fwutil without sudo
SONiC has a concept of "platform components"
this may include - CPLD, FPGA, BIOS, BMC, etc.
These changes are needed to read the version of the BIOS and BMC component.
What I did
The previous implementaion of component.py expect fwutil run with sudo.
When fwutil run without sudo, there are an exception:
```

Fastboot will delay all counters in CONFIG DB, it relies on enable_counters.py to recover the delayed counters. However, enable_counters.py does not recover those non-default counters.

For non-default counters, if it is in CONFIG DB, put delay status to false after the waiting.

Take new hw-mgmt release to SONiC, including:
New features:
1. hw-mgmt: add to PSU FW upgrade tool command to show current FW version
2. hw-mgmt: add to PSU FW upgrade tool support for single-PSU-in-the-system FW upgrade
3. hw-mgmt: add attribute “/firmware” to show FW version of restricted upgradable PSUs only
4. hw-mgmt: Add NVME temperature reports attributes (_alarm/_crit/_min/_max)
Bug fix:
1. psu: redundant i2c_addr attributes being created for psu 3 & 4 in system having only 2 psus.
2. hw-mgmt: in SPC1/2 i2c driver removal is too slow vs. ASIC reset causing non-functional log errors
3. PSU thresholds sysfs changed in 5.10 to “read only” preventing modification (modification required due PSU HW bug)
4. CPLD3 sysfs attribute missing after chip down/up flow
5. sysfs attributes missing when hw-mgmt is restarted (stop/start) within systemd
Release notes can be found from link https://github.com/Mellanox/hw-mgmt/blob/V.7.0020.2004/debian/Release.txt

Why I did it
Fix host image debian package version issue.
The package dependencies may have issue, when some of debian packages of the base image are upgraded. For example, libc is installed in base image, but if the mirror has new version, when running "apt-get upgrade", the package will be upgraded unexpected. To avoid such issue, need to add the versions when building the host image.
How I did it
The package versions of host-image should contain host-base-image.
#### Why I did it
when adding and removing ports after init stage we saw two issues:
first:
In several cases, after removing a port, lldpmgr is continuing to try to add a port to lldp with lldpcli command. the execution of this command is continuing to fail since the port is not existing anymore.
second:
after adding a port, we sometimes see this warning messgae:
"Command failed 'lldpcli configure ports Ethernet18 lldp portidsubtype local etp5b': 2021-07-27T14:16:54 [WARN/lldpctl] cannot find port Ethernet18"
we added these changes in order to solve it.
#### How I did it
port create events are taken from app db only.
lldpcli command is executed only when linux port is up.
when delete port event is received we remove this command from pending_cmds dictionary
#### How to verify it
manual tests and running lldp tests
#### Description for the changelog
Dynamic port configuration - solve lldp issues when adding/removing ports
