Remove IceCube-specific things

[dsschult]

Make the code more modular so IceCube-specific things can be removed into either local config files or a separate repo.

[dsschult]

config files are in. still some things where icecube cvmfs or the condor host is hard coded.

The changes should be in glidein_start.sh. Might be best to write that file automagically when submitting and grab the condor pool host and cvmfs from the config file. Thoughts?

[dsschult]

I'd prefer leaving glidein_start.sh static, and just passing things through environment variables.

My reasoning is that I test a lot with just running this directly to see if the glidein works.

[briedel]

So setting like ${LOCAL_CVMFS} and {CONDOR_GLIDEIN_HOST} from python should work?

[dsschult]

Yes.

There's also the condor passwdfile for connecting to the collector, which is embedded into the glidein. I'm fairly ok with keeping it inside the glidein and just documenting it.

This is security related.
