Create Serverless function using the Import from the Git with Builder Images

Description

As a user, I want to import a Git repository with func.yaml and create a Serverless function

Acceptance Criteria

1. Detect func.yaml in Git repo when user enter the Git URL
2. Read runtime, builder, buildEnvs and run envs value from the func.yaml. func.yaml eg. - https://github.com/vikram-raj/hello-func-node/blob/master/func.yaml
3. Proceed with this flow if the builder value is s2i
4. Allow users to view and possibly edit the environment variables which are shown in func.yaml. Add the buildEnvs and run envs to the resource 
5. if func.yaml is detected change the strategy to Serverless function and do not show builder images in to and  provide a section which allows the user to select the runtime version
6. Do not show the Pipeline and Resources section. Default to Serverless Deployment
7. Add label function.knative.dev: 'true' to KSVC to visualize the Serverless function in the Topology
