Enhance to use host-DBus & State-DB for platform info
Ref 1: " On Fri, Jan 10, 2020 at 6:58 PM [email protected] wrote: Right, we’re on the same page in that regard. This whole syspoll thing was implemented a while back. At the time, we didn’t have the docker-to-host dBus mechanism in place, and we were working with the “restriction” of running the mgmt-framework in the docker and not doing things directly on the host. The PR you’ve linked seems to introduce a host service that writes to the STATE_DB. This seems to be OK, as the PR was merged, so in hindsight we could have explored this option.
We have pending work to extract the data from the DB where possible, make dBus calls to the system when data is not available in the DB, and then get rid of the syspoll/file system approach entirely. However, that code is not part of Release_1.0.

[EXTERNAL EMAIL] Frankly speaking, file system is probably not the best place to carry such dynamic data. It is better to use database to store such data.
Mostly for the data is available in the state db now.
Check the pr here. https://github.com/Azure/sonic-buildimage/pull/3525/files We also have syseeprom in the state db as well.
