* [platform] Add Support For Environment Variable This PR adds the ability to read environment file from /etc/sonic. the file contains immutable SONiC config attributes such as platform, hwsku, version, device_type. The aim is to minimize calls being made into sonic-cfggen during boot time. singed-off-by: Tamer Ahmed <tamer.ahmed@microsoft.com>
