tctl: Add spinner to long running commands [p2]

[feedmeapples]

• Origin issue:

Summary

Adds spinner and progress bar for potentially long running commands. Makes tctl feel more responsive

Basic example

Motivation

Some commands may take long time until they will show output or an error (typically context timeout). This makes tctl feel unresponsive and slow. Proposal addresses these issues adding responsiveness

Detailed design

in doc

Drawbacks

Alternatives

Adoption strategy

not a breaking change

How we teach this

[bergundy]

We should make sure that indicators are only shown when output is a TTY because it will conflict with piping.

It'd be nice to have a flag to dictate this as well.

yup, this is covered

Updated the terminology to "spinner" and "progress bar", specified --no-progress in the doc (similar to npm --no-progress)

[feedmeapples]

this proposal is on hold rn, focused on implementing higher priority proposals and releasing tctl. Afterwards planning to finish and implement this proposal

[bergundy]

This is outdated. Closing due to lack of motivation.
