The framework/ssh.go code was heavily used throughout the framework
and could be useful elsewhere but reusing those methods requires
importing all of the framework.
Extracting these methods to their own package for reuse.
Only a few methods had to be copied into this package from the
rest of the framework to avoid an import cycle.

Disable symbol resolution by pprof in profile-gatherer
Because otherwise it is failing while trying to symbolize, due to lack of a kube-apiserver binary locally (as noted by @wojtek-t) within the job pod:
```
Local symbolization failed for kube-apiserver: open /usr/local/bin/kube-apiserver: no such file or directory
```
This does seem to still produce a graph with all named references - so it seems fine to avoid it. The [documentation](https://github.com/google/pprof/blob/master/doc/pprof.md#symbolization) says:
```
pprof can add symbol information to a profile that was collected only with address information. This is useful for profiles for compiled languages, where it may not be easy or even possible for the profile source to include function names or source coordinates.
```
So my feeling is that for golang, the function names, etc are included in the profile source.
