replaces meta data for operator will throw fatal error when no previous version of operator is found.

[aneeshkp]

If the replace operator is mentioned in CSV file without actually having an older version of the operator in the marketplace, the CatalogSourceConfig fails to run due to a fatal error

If it doesn't find the replacement, it should ignore and continue instead of throwing a fatal error.

Message: time="2019-04-29T17:35:06Z" level=fatal msg="error loading manifest from remote registry - kubevirtoperator.0.17.0-alpha.0 specifies replacement that couldn't be found" port=50051 type=appregistry

In the below example "replaces: kubevirtoperator.0.16.2" is causing the fatal error since there is no operator to replace.

Would you mind moving this to operator-registry?

Originally we thought it was useful to know if you accidentally publish an operator that doesn't replace the right thing, but there are definitely valid use cases for publishing catalogs that don't contain a chain back to the first operator in a channel
