 ✗  unable to create or update component: unable to create PVC: unable to create PVC: PersistentVolumeClaim "odo-projects-dotnet60-example-app" is invalid: metadata.labels: Invalid value: ".NET": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue',  or 'my_value',  or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?')
Cleaning resources, please wait

the devfile.yaml has projectType: .NET and odo is generating k8s rousrces with app.openshift.io/runtime label with value that is that same as projectType

odo should clean projectType value first to make sure that it can be used as in labels.

If the string starts with a '.', cleanup should change it to 'dot' or 'DOT'.
This might break the icons on Dev console, but that's a risk we're willing to take, better than breaking odo.

Do the same anywhere we are using Devfile fields(such as language and projectType) for labels.

Validation checks:

• a valid label must be an empty string or consist of alphanumeric characters, '-', '' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue', or 'my_value', or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9.]*)?[A-Za-z0-9])?')
• length check <=63
