Upgrading KUDO will cause "kudo install" failures given incompatible local repositories

[mpereira]

What would you like to be added:

We should either have KUDO automatically handle updating local KUDO repository
files (~/.kudo/repository/repositories.yaml ) or to include instructions in
the CHANGELOG update section to ask users to remove possibly incompatible local repositories.

Why is this needed:

I updated KUDO from 0.8.0 to 0.10.0 which caused kubectl kudo install cassandra
to fail with:

Error: failed to install cassandra-operatorversion.yaml: installing OperatorVersion: OperatorVersion.kudo.dev "cassandra-" is invalid: metadata.name: Invalid value: "cassandra-": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')

The solution was to remove my local KUDO repository file:

rm -f ~/.kudo/repository/repositories.yaml

After that, kudo install succeeded.
