Consolidate host agent path env vars into single AGENT_FILES_ROOTDIR

Browse Source 
Replace AGENT_KERNEL_PATH, AGENT_IMAGES_PATH, AGENT_SANDBOXES_PATH,
AGENT_SNAPSHOTS_PATH, and AGENT_TOKEN_FILE with a single
AGENT_FILES_ROOTDIR (default /var/lib/wrenn) that derives all
subdirectory paths automatically.
