zwe diagnose: shell only and no doc

[Martin-Zeithaml]

1. Shell version is working only
2. There is no doc update for this feature

Add a text to shell version of diagnose command:
zowe/runtime/2120/bin/commands/diagnose: echo "echo 'hello, world'" >> index.sh

Call diagnose with --configmrg
zowe/runtime/2120/bin: ./zwe diagnose -e "ZWEL0111E" --configmgr

Shell version is executed:

no doc update because doc automation is broken. i need to fix it. there was some code conflict which broke the bot.

what is the reason to make the shell version? its fine but currently we have both TS & shell because we were moving away from shell. personally I wasn't going to write more shell, but maybe someone else would & maybe there is a good reason to?

Probably the wrong description of a problem, diagnose is already in shell and TS.
But no matter what, only shell is executed.

There is missing in the index.sh: IF USE_CONFIG -> run _CEE_RUNOPTS... configmgr -script ...
