README: example output closer to real output

Introduce "deploy" and "delete" commands
readme: sections on local usage, repeat usage and deletion
cli 'delete' command stub added
Merge pull request #2 from frodenas/openstack

Added support for Openstack
add 'ssh' command
add 'delete' command to delete current micro-bosh
abstract local pub/priv keys into local_ssh_key_paths
'ssh' command returns exit code returned by ssh cmd
document delete command
refactor ssh command method into highlevel helper
initial scaffold for implementing 'delete --all' mass destruction
current username is default bosh username
introduce --private-key to allow specific private key file for inception VM
Wait a few seconds before trying to create new user for bosh
Skip inception preparation if already done
Pass user/pass to CLI

I think it was blocking. Unsure.
explicitly use bosh gems
deploy --git will install bosh from git source
If remote script has non-zero exit, deploy stops

Finally!
bump to v1
