e2e: Easier to follow log

[nirs]

Additional log cleanups split from #1628:

• remove the file:line since it make it harder to follow the log and does not add much value.
  • it could be nice to have it we could move it to the end of the log https://github.com/uber-go/zap/discussions/1471
• Remove unhelpful noise from test name "Deploy", "busybox"

Summary from discussion with @raghavendra-talur:

We want to replace the current format:

{deployer}-Deploy-{rbd|cephfs}-busybox

With:

{deploy|statefulset|daemonset|vm}-{block|file}-{deployer}-{volrep|volsync}

(I'm not sure about the order)

So the tests are about:

• The workload
• The volume mode (different modes need different deployment script for busybox)
• The way the workload is deployed
• The way we protect the workload

And not about specific storage provider (rbd, cephfs) - Ramen is storage agnostic.

The config determines the particular storage to use for the test. The same test will work on drenv, openshift, k8s, with any compatible storage,
