Add more choices to the "srb init" question

[jasnow]

Problem

Only one choice, yes, to do for "srb init"

Proposed solution

Suggest that you add more choices to the srb init question so users could better self-diagnosis init problems. They could provide more information in issue reports too.
The current srb init question is:

• Would you like to continue? [Y/n]

SUGGESTIONS: Like H, V, S, E, I where

• H(elp) would provide "srb init" usage/help information (existing issue: srb init --help should provide documentation, but not do anything #1003)
• V(erbose), T(ell me more), D(ebug) would add more detailed information such as the phases milestones, etc.
• S(ilent) turns off all sorbet-generated warnings and errors so you can see where the messages are coming from
• E(rrors) keeps only sorbet-generated errors
• I(nfor) turns off all sorbet-generated information-only warnings.

Example: rails app:update has multiple choices: (enter "h" for help) [Ynaqdhm]

One last thing - you can break into request into multiple PRs.
Thanks

Found that I can separate the stdout and stderr output into separate files but that also losses context.

Wishful thinking.
