Auto-deduced YAML test case names collide when the file name includes more than one dot

[mustafakemalgilor]

Assuming the following YAML file names, the auto-deduced test case names are the same even though the file names are different:

• lp1896125-17.0.0.yaml
• lp1896125-17.0.1.yaml

These files yield lp1896125-17 as the test name, which leads to a name collision.

Ideally, the code should strip away the file extension, sanitize the remainder, and use that as a test name.

@mustafakemalgilor while we should probably fix that, I feel it makes sense to give the files meaningful names so that you can tell what they are doing from their name so e.g. suffix like _pass.yaml _fail.yaml is what i usually use.

Sure, in this context the suffixes are version numbers for different keystone releases I'd like to test the scenario against. I wanted to be verbose on test cases for ensuring that the new version comparison logic works as intended for non-superficial use cases.
