Remove no use option parameters for template-validate

template-validate only validates the template body, so
option parameters here is no use, if you want to validate
a template with parameters, you can use stack-preview

Append extra space after command in bash_completion

Unlike NovaClient or other Clients in OpenStack, 
there is no space append after command in Heat Client.
That means if I try to run 'heat stack-delete', I have 
to manually append the space and then append the thing 
I want to delete.
This correction will help Heat Client to be more 
convenient for operators.
