DeleteFruVpd:Conditional FRU deletion

This commit adds a check in deleteFruVpd API to prevent deletion of FRUs
which are present and whose presence is handled by external service.

```
Test:
- On Everest system, see fan0 VPD is present on PIM
- Set "Present" property of fan0 to false using busctl
- See fan0 VPD is cleared from PIM
- Set "Present" property of fan0 to true using busctl
- Execute DeleteFruVpd API from vpd-manager D-Bus interface
- DeleteFruVpd fails
- Check VPD of pcie_card2 using vpd-tool and see it is present
- Execute deleteFruVpd on pcie_card2 and see it is successful
```

Listener:Implement Present property callback

This commit implements Present property callback in Listener. For
hotPluggable FRUs whose present property is toggled by external
application based on their actual presence detection, vpd-manager needs
to monitor "Present" property and collect/delete FRU VPD accordingly.

Test:
```
- On Everest system, toggle Present property of fan0 from busctl
- Observer callback getting triggered
```

Continue execution on any GPIO exception

In case there is any issue with reading of presence GPIO, the code
should check if the required EEPROM file exists.
If found and can be parsed then instead of exiting collection for the
FRU, the code will log an informational PEL for the error and will
continue with the execution.
This is required so that we don't exit collection for an intermediate
error when the collection can be successfully done.

Update PELs while parsing FRU

Severity of PEL needs to be updated as informational in case any
of the FRU collection fails for reason other than EEPROM or data
failure, for which the severity will be handled by the specific parser.

This is done as successful collection of a FRU other than system VPD
is not a mandatory condition to bring BMC to ready state.

In case of failure in the processing of pre action, to figure out what
failed in the flow, informational PEL is added while processing
pre-action tags.

No error in case the file is not found and pre-action was not required
as FRU can be actually absent.

Empty map is also not considered for logging PEL in worker as
respective parser should take care of any error and log PEL at their
end.
