Add support of the pensando-dpu platform to generate-dump utility.

[Siddhu27]

What I did

Add support of the pensando-dpu platform to generate-dump utility to collect platform-specific dumps on Pensando DPU.

How I did it

Extend platform-specific section of generate-dump utility

How to verify it

Run "show techsupport" command to generate dump file. Verify that {dpu_container}_techsupport directory exists in the created dump file.

Previous command output (if the output of a command-line utility has changed)

New command output (if the output of a command-line utility has changed)

show techsupport command output logs:-

@prsunny added the show techsupport command and generate_dump with -n option logs.
