Have functionalities in red / green / grey depending on test execution results, stream by stream

# Have functionalities in red / green / grey depending on test execution results, stream by stream

## Context:
Ara provides the list of functionalities, with test coverage. Actually, functionalities are "just" a list managed with a tree.

## Expected:
Depending on linked last execution test results, functionalities are with a colour background.

Functionality 1 linked with tests that are all "Passed" on last execution results: the functionality 1 has a GREEN background color.

Functionality 2 linked with tests that are all "Failed" on last execution results: the functionality 2 has a RED background color.

Functionality 3 linked with at least ONE test failed on last execution results: the functionality 3 has a RED background color.

Functionality 4 linked with 0 test: the functionality 4 has a GREY background color.

Functionality 5 linked with only ignored or draft tests: the functionality 5 has a GREY background color.

Except for Functionality 5 case, please take in account only VALID test executions (not ignored or draft).
Discarded executions are not taken in account.

The functionality must offer the possibility to see colors for dev, stab or master releases.
