[Feature] Add support for basic package management in spacectl

[shubham4443]

Create additional client generation commands:

• spacectl package init - To create sc.yaml config file and required folder structure. Folder structure includes operation folder where client stores graphql files and resources folder where space-cloud generates CompiledGraphqlSources CR.
• spacectl package apply - A command which is equivalent to the helm upgrade command

Initialize Package: spacectl package init

• Creates an sc/package.yaml file in $PWD
• File contains:
  • Name of package (name) - Default (Current working directory name)
  • Labels (labels) - Default set of labels to be added to each resource being applied- Make sure we implicitly add a label space-cloud.io/package=<package-name>
  • Output:
    • Client Gen language - E.g. rtk-query
    • Directory of generated files - Default (sc/output)
  • Directory of source files - Defaults (sc/resources)

Flags or survey:

• --name/ -n (Defaults: Working directory name)
• --language/ --lang/ -l
• --output-dir/-o
• --resource-dir/-r

Apply resource in package: spacectl package apply

• First login
• Retrieve all CRs SC. This will require a new API on the backend (put this in admin manager)
• Load resources from resource directly and inject labels into them
• Calculate deltas between resources received from SC (for current package) vs those present in local resources directory
• Apply the delta to SpaceCloud.

Get all resources in package: spacectl package get all

• First Login
• Retrieve all CRs from current workspace from SC
• Print all resources as a table on the screen

Get all resources of a particular kind in package: spacectl package get <kind>
