add retries for get_network_adapter_name_by_mac_address

[noliaoliao]

for my testes, sometimes cloudbase-init can't initialize interface correctly, and lookup the log we can see the exception as below

I guess this is because when cloud-init run, the NICs are don't seen by OS, so we should add more retries here, just like this commint

Hello @noliaoliao ,

If your system is slow (I assume it is baremetal), I suggest you to set the cloudbase-init service to automatic delayed start, to make sure this kind of issues does not happen.
