Option to customize the setup of basic cluster

[rahulrai-in]

Is your feature request related to a problem? Please describe.
Currently, the extension creates its own version of a basic cluster. I would like to customize the behavior of the command to define a basic cluster.
Also, the name of the basic cluster should follow a standard so that I can identify the test clusters in the portal or extension without having to explore their workloads.

Mention what platform you want to support the new feature
VSCode

Describe the solution you'd like
The cluster setup parameters and the naming pattern should be read from a configuration file, such as a dotfile, for ease of use.

Describe alternatives you've considered
Use the CLI to create a cluster. Commit the script to create a cluster in the repository to share with other developers.

Additional context

1. Developers can create their own clusters and not delete them afterward.
2. Without a naming convention, it is hard to identify the clusters that can be safely deleted.

☕️💡 There is whole lot of cluster create effort which will happen under #294 - I think it will be worth to keep this issue in mind as fyi as well, @hsubramanianaks and cc: @peterbom

☕️🙏🎊 Given we have delivered an improved UI and other improvements via #241 & #294, I recently went through various discussions realised that we should confer this to open discussion now.

I feel we should avoid creating replication of portal experience so what we have at this stage is nice to have from vscode experience, I am also not want this to be closed either in case we have enough community support its worth to scope this.
