[sonic-ztp] Add dynamic port breakout(DPB) to ZTP temolate

[dennis0113]

- Why I did it
To support DPB with the ZTP template.

-How I did it
Generate 'BREAKOUT_CFG' when dynamic port breakout(DPB) is supported on the platform.
Revise the ZTP template so that the DPB CLI can be executed when config is generated from the ZTP template.

-How to verify it
Execute DPB cli when the config is generated from ZTP template.

@dennis0113 Can you please confirm that the BREAKOUT_CFG included will be compatible with the PORT table defined in the same template? Also it is to be noted that you are just trying to use the default port breakout mode to light up an in-band port link.

@dennis0113 Can you please respond to my question.

[dennis0113]

Sorry for the late response.

I consider that BREAKOUT_CFG can be compatible with the PORT table.
Because PORT table will be generated from "platform.json" rather than "port_config.ini" if the "platform.json" exists.

And I am not trying to use the default port breakout mode to light up an in-band port link.
I just want the SONiC Cli for the breakout command can be executed even if the config is generated from ztp template.

Thanks
