Isolate all the Runfunctions to API & Represent output as YAML or JSON or Table

[bishal7679]

Part of fixing #11

Previous State

• Previously, only JSON output was supported
• Codebase was unstructured
• Logging the error messages was not so good

Current Behaviour

part 1

• Restructured the whole codebase with efficient manner
• Separated all the RunFunctions to api folder apis.go which will eventually be used by cobra commands
• Separated all the useful packages like util to internal/pkg and under logger folder added nicely formatted logger for showing Error messages/Info beautifully
• Also isolated all the struct used by all RunFunctions to config folder as resourceStruct.go

part 2

• Support YAML, JSON and Table output format as suggested
• Making Table output default
• Added -o wide: This parameter allows us to display extra information (if needed, otherwise -o wide should have no effect)
• Also solving the create project flow into create_project.go file by adding cobra Args and making the public as false default [part of Improve Creating Project flow. #12]

Remaining feat to add [Need some discussions on these]

• --sort-by: This parameter allows us to sort the output based on the resource attribute we specify.
• Support of JSONPath, or GO template.
• -f, --field-selector==: This parameter allows us to filter the output using some resource attributes.
