* hcl2template/addrs.ParseRef will parse a reference and tell for example if we
are referring to a variable and its name, for now it can only do that and in
the future it improved when we need to most of it is from the TF code. This
is used to tell wether a variable vas referenced in a variable validation
condition; for now.
* Added Validations blocks to the hcl2 Variable struct and code to
parse/validate that.
After testing it was found that once an session is terminated via an
instance restart, console termination, or SSM agent restart. Any active
session will essentially be terminated and unusable. So knowing that it
is always best to start a new session and let the old one timeout get
terminated.
