TECH-417: Added sorting support for /report list

[dborowiecki]

Ticket: TECH-417

Supported sorting keys:

sort.testApp
sort.testSuite
sort.sourceBranch
sort.overallCompatibility

[mgrochalskisoldevelo]

The only thing to discuss I see is:

When we invoke the request multiple times data in compatibilities may be returned in different order. What do you think about it @dborowiecki should we add some kind of built in sorting mechanism to avoid it? except that lgtm

@mgrochalskisoldevelo good catch with the compatibilities inconsistency. I don't think it's related to changes in PR. However, I added fix to the pipeline in this PR.

When you've mentioned compatibilities, I've noticed that we are sorting the projects by their ID. I think we could sort by saveTime so most recent products are shown first, but we need to discuss it with commitee first.
