[BFN] Implementation API for platform component (sonic-net#10180)

* [BFN] Implementation API for platform component 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 Create components.py module Add funcion for reading componet version to thrift interface How I did it The previous implementaion didn't have platform components API, so fwutil return an empty list. After implementation of the platform component API, we have actual list of platform components and firmware versions How to verify it Run manually 'fwutil show status' or run unit tests Previous command output Chassis Module Component Version Description ------------------------ -------- ----------- --------- ------------- New command output Chassis Module Component Version Description ------------------------ -------- ----------- --------- ------------- Chassis1 N/A BIOS 1.2.3 Chassis BIOS BMC 5.1 Chassis BMC Signed-off-by: Taras Keryk <[email protected]> * [BFN] Implementation API for platform component 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.
