SEA-265 Improvement of configure task

[GwendalLaurent]

Summary

This PR is linked to the PR SEA-265 Improvement of configure task on rebar3_grisp

In this PR a few improvements have been done for the configure task:

• The grisp.io token is now trimmed at the beginning and at the end of the user input
• A setting was represented as a tuple internally. It is now represented as a record
• Some prompts now have hint/comments to explain them. They are displayed on top of the actual prompt. They are optional
• The default values are displayed in blue. The comments are displayed in grey and warnings are displayed in orange
• Internally, asking for an input is done through an event. This wasn't the case before

How to test ?

To test this PR you will need a local setup. Indeed, since the changes aren't pushed on the main branch the version of the plugin globally installed on your computer won't reflect the changes made for this PR. Thus we will need to use a throw off grisp project and use the _checkouts folder to use the correct versions of this repo as well as the rebar3_grisp repo. Both of them should be setup to checkout the branch named SEA-365-grisp-conf-upgrade

Example of the overall look of the task

Fix hint

[ziopio]

Just as a note, but is not needed.
This does not protect from " that if left unescaped will lead to crashes in the config file.
And if the token is between "" will also crash -> <<""mytoken"">>

The latest change:

Suggested change

	unicode:characters_to_binary(Trimmed);
	Whitespace = unicode_util:whitespace(),
	Trimmed = string:trim(String, both, Whitespace ++ [$"]),

should fix this issue by removing the whitespaces and unescaped "

It looks great! As soon as this is merged, I'll update the wiki tutorial and grisp_manager so everything looks the same :)

The only thing that's a bit strange to me is having the defaults in quotes.
