Required libraries can be installed silently #492

[Vassiliy-Kudryashov]

Description

Getting rid of all needless Yes/No and OK/Cancel dialogs that dramatically slowdown first time use case

Fixes#492

Type of Change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

Manual Scenario

Prepare environment with clean config (e.g. no required libraries (JUnit/Mockito etc. in dependencies, empty or absent resources folder) and run tests generation. Single OK click does everything now.

Checklist (remove irrelevant options):

• The change followed the style guidelines of the UTBot project
• Self-review of the code is passed
• No new warnings

I think we should make an extension class be a little more carefully implemented and clear to newcomers.
Also I have two questions not related to code quality.

@alisevych I suggest to test this functionality carefully in different projects (Maven, Gradle, Idea) of different versions. Potential breaking changes.

@EgorkaKulikov@Vassiliy-Kudryashov
I've published plugin from this branch as archive and tested it on IDEA Ultimate 2022.1.3

During testing I faced IndexNotReadyException (see #273) almost every time I've tried to generate tests in a manually created folder in IDEA project.
It was thrown on the first UTBot test generation after IDEA restarted.
On the next calls the tests were generated to the new test root correctly.

No other issues found so far.
As @Vassiliy-Kudryashov suggested, merging latest changes from main into this branch can make sense.
So could please notify me after update? I would check some more cases.
