Small fix for ec2 validate_certs option

Adding 'validate_certs' option to EC2 modules

Also removing validate_cert option from the cloudformation module docs,
as it does not use the standard ec2 connection.

This filtering is done in both the module invocation logging and in
the regular verbose() logging output.

When disabled, the boto connection will be instantiated without validating
the SSL certificate from the target endpoint. This allows the modules to connect
to Eucalyptus instances running with self-signed certs without errors.

Fixes #3978
