Lavatory doesn't read in policies with . in name

[APemberton1]

Lavatory cannot read in the policy of a Artifactory repo name with format my-artifactory.repo, e.g. a created policymy_artifactory.repo.py doesn't get read in.
looks like we need an update to:
https://github.com/gogoair/lavatory/blob/master/src/lavatory/utils/setup_pluginbase.py#L51
to replace the . in the policy name

As a workaround you can overwrite Artifactory instance's repo_name attribute value before performing any query in your purgelist() definition.

For example if your Artifactory repo's name is my-artifactory.repo, you could create a policy module named my_artifactory_repo.py and define purgelist() as:

def purgelist(artifactory):
    artifactory.repo_name = "my-artifactory.repo"
    ...

You'll have to use the policy module name as --repo argument when invoking lavatory purge on the command line though.

Example:

lavatory purge --repo my_artifactory_repo ...

Not ideal, but better than nothing.
