Support for optional dependencies between installed components

[dgolovin]

As a developer who is installing tools for everyday work I want to have more control over what is going to be installed and be able to deselect specific components that is not breaking dependents when missing. Example for optional dependencies:

1. CDK related tools in DevStuido requires rsync.exe which is part of Cygwin, but studio will continue to work except oc sync related features;
2. Fuse Tooling and Fuse run-times
   On opposite side there are hard dependencies like DevStudio requires Java VM to run.

This is also useful for guided development when some dependencies like run-times might be included be default into guided development, but it would be possible skip installation if they not wanted.
These optional dependencies might have default state selected/deselected where deselected optional deps in guided development would let to request additional optional component to be installed in opposite to use case above.
