What happened?

#Enter text here.
The GCP/hosts.py script was updated to python3 and the requirements for running the script are missing as well as documentation on how to use the script.

The missing packages include: pycrypto >= 2.6, apache-libcloud.

**Note: pycrypto may not be necessary. 

#See the troubleshooting documentation (https://github.com/openshift/installer/blob/master/docs/user/troubleshooting.md) for ideas about what information to collect.

There is no troubleshooting documentation or documentation at all in this directory. Clean this up by adding documentation about the script as well as some of the required and option environment variables used through out the script.

REQUIRED:
GCE_EMAIL
GCE_PEM_FILE_PATH

OPTIONAL:
GCE_PROJECT
GCE_ZONE
GCE_INI_PATH
GCE_TAGGED_INSTANCES
INVENTORY_IP_TYPE

# If the installer fails to create resources (https://github.com/openshift/installer/blob/master/docs/user/troubleshooting.md#installer-fails-to-create-resources), attach the relevant portions of your `.openshift_install.log.`
# If the installer fails to bootstrap the cluster (https://github.com/openshift/installer/blob/master/docs/user/troubleshootingbootstrap.md), attach the bootstrap log bundle.
# If the installer fails to complete installation after bootstrapping completes (https://github.com/openshift/installer/blob/master/docs/user/troubleshooting.md#installer-fails-to-initialize-the-cluster), attach the must-gather log bundle using `oc adm must-gather`

# Always at least include the `.openshift_install.log`

Removed the unnecessary files rather than trying to fix them since it wouldn't work without back porting old files.

The script in question can be removed solving this BZ. The script requires python2 before and that can also be removed from dependencies.
