Valid service from catsrc with periods in name

Problem: Creating a catalogSource with a period in the name is valid as
the Kuberenetes API catalogSources to adhere to the following naing
conventions:
- Start and end with a lower case alphanumeric character
- Consist only of alphanumeric characters, `.`, or `-`

Unfortunately, the service created by OLM for the catalogSource must
adhere to the following naming conventions:
- Start and end with a lower case alphanumeric character
- Consist only of alphanumeric characters or `-`

This causes OLM to constantly recreate the catalogSource as the service
it attempts to create is rejected from the Kubernetes API service due to
the `.` in the name.

Solution: When naming the service, replace all instances of `.` in the
name with `-`.
