Remove parser.py

[Ethan Lynn]

Remove heat/engine/parser.py, all the classes are split into stack.py and template.py

https://github.com/openstack/heat/blob/master/heat/engine/parser.py

from heat.engine import stack
from heat.engine import template

# Note: these classes are here for backwards compatibility.
# New uses of the Stack class should use stack.Stack().
#
Template = template.Template
Stack = stack.Stack

    Classes in parser.py are already split to stack.py and
    template.py, it's not recommended to import it.
