[SPARK-22992][K8S] Remove assumption of the DNS domain
## What changes were proposed in this pull request?
Remove the use of FQDN to access the driver because it assumes that it's
set up in a DNS zone - `cluster.local` which is common but not ubiquitous
Note that we already access the in-cluster API server through
`kubernetes.default.svc`, so, by extension, this should work as well.
The alternative is to introduce DNS zones for both of those addresses.
## How was this patch tested?
Unit tests
