Subject: [PATCH] [vs] add information about features to config db (#7857)

vs has components from swss, bgp, teamd and nat. This table is needed by this change https://github.com/Azure/sonic-utilities/pull/1554.

Because Azure/sonic-utilities#1554 requires "config warm_restart enable FEATURE" and the FEATURE has to be in feature table.
