Harshavardhana 6efee2072d objectLayer: Check for format.json in a wrapped disk. (#3311)
This is needed to validate if the `format.json` indeed exists
when a fresh node is brought online.

This wrapped implementation also connects to the remote node
by attempting a re-login. Subsequently after a successful
connect `format.json` is validated as well.

Fixes #3207
