refacort deploy.yml and add jsonschema to validate it

1. add adapter type in deploy.yml
Do not rely on the pod's name to detemine whether impi or libvirt
should be used.

2. increase disk size in deploy.yml
The disk sizes should be bigger than 102400 mega-bytes according to
the minimum of root_lv_size in upstream openstack/daisycloud-core.

3. add schemas.py
Use jsonschema to validate deploy.yml
