Small updates.

These scripts start a new test server on HPCS

Also do general HPCS operations.

> cp conf/hpcs.conf.sample /tmp/hpcs
> edit /tmp/hpcs
> export STACKATO_HPCS_CONFIG=/tmp/hpcs
> ./bin/nova-hpcs           # help
> ./bin/nova-hpcs floating-list
> ./bin/stackato-test-server new -a <floating-ip-address>
> ./bin/nova-hpcs list
> ./bin/stackato-test-server kill <instance-id>
