Was updating the password all the time which would invalidate any of
the users existing tokens and might cause temp auth issues.
This change adds a token-get check to allow the password update to be
skipped if it's already current.
Broke down the provider CLI Environment into three categories (from two).
* Boot is using the bootstrap token
* Admin is using admin endpoint and admin creds, only used by EC2.
* User is using api endpoint and user creds, used for token-get.
The current provider design has the basic input parms (user_name,
user_password, tenant_name) and the ones needed only for implementation
all required. I think the implementation ones should all be optional
as the provider can easily get them for itself. On that thought, with
this change I started with allowing identity_endpoint to be optional.
It is used only for the create_user and create_ec2_credentials ascions.
I believe this is the right direction for this provider.
Having said all that, I also know that we have begun work on the client
cookbook to have providers for many OpenStack resouces like keystone
items. Since that is not far enough along yet, I decided to make the
changes in the currently used identity provider.
Added missing EC2 tests.
Added logging of the CLI Environment.
