RFE: Request for multiple url to be configured in global ztpserver.conf file

[shravya-k]

In a situation where new switches need to be provisioned are behind NAT rules during the execution of the bootstrap script the new connections needed to fetch the config file might break in a situation where the ztpservers requests are NATing on the way.

Giving optional urls to failover when the 1st url does not work is one way to solve the problem.

Following are certain logs when a new Arista devices are provisioned and the requests undergo a destination NAT from 172.18.254.120 ----> 10.58.76.198.
