Interface with no outbound access to IMDS will fail

[joeysk2012]

An internal customer reported a issue when the IMDS not able to reach the IMDS server if the default interface becomes an interface in which IMDS is not able to reached such as a local interface on the customer on-premise. The working fix is to use an interface which can call IMDS and use that as a parameter to curl --interface and store this interface name between calls.

Submitted a Draft PR and testing these changes:
#116

I will follow up once review and testing is completed.
