Do no re-validate parameters for existing stacks

This patch disables validation of stack parameters values when
loading existing stacks from the database. The old behavior was
to always validate stack parameter values when initializing a
Stack object. However, this causes problems especially with
custom constraints when a constraint could be fulfilled during
stack creation but cannot be fulfilled at a later point (e.g.
when a flavor or keypair has been deleted). In such a case,
the existing stack became completely unusable.

This patch changes the behavior to not do parameter validation
for existing stacks. The assumption is that validation at stack
creation time should be sufficient to make sure the stack is valid,
so only valid stacks end up in the database. Therefore, validating
parameters again when loading stacks is not really required.

Use str_to_num for Number parameter

Current implemenation method 'value' convert all input parameters. But
should ignore type Number, because it may round value with float type.
Also this logic is already implemented in str_to_num method. This patch
forces NumberParam class to use str_to_num in value method.

Replacing variable logger on LOG

Commit https://review.openstack.org/#/c/94255/1 introduces check for
translating log messages. This check uses in pattern name 'LOG', so in
heat code also should be used this name intead of 'logger'. Also same
name is used in other projects.
