The idea is:
Allow specifying a full domain under ServiceNow credentials.
My use case:
We host our own ServiceNow, meaning it runs on its own domain.
I think it would be beneficial to add this because:
This would allow us to use the ServiceNow node!
We currently can’t use it since credentials can only receive a subdomain
Hey 
Would appreciate if anyone could take a look and approve the PR.
Thanks!
