Support default resource type in User Preferences

Problem:

Currently in the Import flow, we default to Deployments. If developers want to use Deployment Configs or Serverless as a default, we force them to make that selection every time. Additionally, if Serverless is installed, we should default to Serverless by default!

Why is it important?

• Helps to promote the use of Serverless functionality.
• Improves the user experience. Users who don't want the OpenShift default will not have to continually change the resource type when the use this flow.

Acceptance criteria:

1. User is able to set their Resource preference for Import flow via User Prefs
2. Users default setting is Deployment when the Serverless Operator is not installed
3. Users default setting is Serverless when the Serverless Operator is installed
4. Users experience in the Import flow includes having the default set in Users Prefs as the default Resource Type
5. Users experience in the Import flow includes the ability to change the resource type
