monokle: Convert resource names to lowercase to avoid InvalidValue error

Describe the enhancement you’d like to see

When I try to deploy a resource using the resource template and provide a name that has uppercase characters, it fails to deploy with the error:

Invalid value: "BasicDeployment": a lowercase RFC 1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character

It would be better if we could either:

• force the user to enter the name only in lowercase alphanumeric characters on the template creation screen - preferred
• internally convert the user input to lowercase

That way, we can avoid this error and the user doesn’t have to rename the deployments to deploy them.

Additional context

I get the following error when I’m trying to deploy a deployment that has uppercase characters.

Title: Applying BasicDeployment to cluster kind-kind failed Description: The Deployment “BasicDeployment” is invalid:

• metadata.name: Invalid value: “BasicDeployment”: a lowercase RFC 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?)*’)
• spec.template.spec.containers[0].name: Invalid value: “BasicDeployment”: a lowercase RFC 1123 label must consist of lower case alphanumeric characters or ‘-’, and must start and end with an alphanumeric character (e.g. ‘my-name’, or ‘123-abc’, regex used for validation is ‘a-z0-9?’)
