Go binding cleanup and example app

[KeithWiles]

Here is a list on what I cleaned up:

• Simplify the usability and utilize the full JSON-c configuration.
• Remove some files that are combined into others and rework a few areas to make it easier to understand.
• Rework RxBurst/TxBurst/… to take a lportID instead of passing a method pointer.
• Cleaned up a number of allocations around LPort as this data is static after startup.
• Remove all of the underscore variables and convert them to Go variable names.
• Add the start of documentation to all of the files. Needs more work.
• Added a few more helper routines to parse a slice to packets or objects.
• Update the example/fwd application to utilize the JSON-c instead of JSON
• Remove the -port option and use the JSON-c thread section to identify the lports attached to a given thread
• Add support for using the JSON Threads section for starting threads an assigning lports to those threads.
• Use the tview Go library to display the stats in a easier to read format.
• Update the test routines to poll more than just one lport.
• Updated the cne/run_test code and script to test more functions.
• Updated the example/run_fwd script remove the -port option with other cleanups.
• More minor changes for refactoring and cleanup.

The super linter is executing on the XXX_test.go files and it should not unless we can figure out how to make it work. I do not think is a big problem, so I would like to figure out how to exclude *_test.go files.

The next problem is the Super-Linter does not appear to understand import "C" statements and that causes a number of failures.

This PR needs #153 to be complete, but I could not find how to make this PR dependent on PR 153.

setting VALIDATE_GO: false https://github.com/CloudNativeDataPlane/cndp/blob/main/.github/workflows/super-linter.yml#L33 would prevent Go files from being linted

These issues seem to be related to the failures shown by the Go linter
golangci/golangci-lint#1176 related to the

could not import C (cgo preprocessing failed) (typecheck)
import "C"

https://github.com/github/super-linter/issues/1599 - related to the the undeclared name failure

[maryamtahhan]
