Disable CEIP prompt for tanzu 'version', 'ceip set' and 'config set' commands

[prkalle]

• Disable CEIP prompt for tanzu version, 'tanzu ceip set' and 'tanzu config set'
• Also updated the short/long description for CEIP command

What this PR does / why we need it

This PR would disable the CEIP prompt for "tanzu version", "tanzu config set" and "tanzu ceip set"

We need it for the below reasons:

• 'tanzu version'(common first command to run),
• 'ceip set' (not a good UX to prompt user who is trying to set the CEIP configuration)
• 'config set' (would be a chicken and egg issue if user tries to set CEIP configuration using "tanzu config set env.TANZU_CLI_CEIP_OPT_IN_PROMPT_ANSWER yes")

Which issue(s) this PR fixes

Fixes #189

Just a minor nit. We can address it as a followup as well. Otherwise LGTM.

Nit: If we don't add as code comments, I suggest we put in the "What this PR does / why we need it" PR description on the reason(s) we elected to special-case these commands so we don't forget. (this is a "why we need it" part :-) )
