Minor: Do not truncate SHOW ALL in datafusion-cli

[alamb]

Which issue does this PR close?

N/A

Rationale for this change

When I want to see all the config options in datafusion CLI I use SHOW ALL.
However there are more than 40 rows (the default before truncation) and I almost
always forget to set --maxrows and thus can't see all of them:

I would like to see them all

What changes are included in this PR?

1. Refactor code for adjusting PrintOptions into its own structure
2. Add case for SHOW VARIABLE

Are these changes tested?

I tested this manually

Are there any user-facing changes?

I can see all variables now with SHOW ALL:

I extracted the existing code to update the print options based on statement into its own structure which I think makes it clearer what is going on here

Thanks for the review @Ted-Jiang 🙏
