Fixes for --help-examples

[KevinLoesch1]

What It Does This fix corrects several commands where the --help-examples fails to include the group in the example. This pull request will fix issues https://github.com/zowe/zowe-cli/issues/1715 and https://github.com/zowe/zowe-cli/issues/1865.

How to Test Issue the --help-examples command at the group level. It should now display the group properly. For example, zowe zos-jobs --help-examples should display the group and command in the examples.

`

Submit the JCL in the USS file "/a/ibmuser/compile.jcl":

  $ zowe zos-jobs submit uss-file "/a/ibmuser/compile.jcl"
