[9.1] Add explicit versions in the branches.json (#129637) (#133338)

Versions from branches.json are now used for calculating unreleased
versions for BwC tests.
Gradle task added to modify branches.json.
Possibility to add, remove and update branches in the file with
the version field added next to the branch.
BwC test configuration has been changed to use changed branches.json
file to calculate unreleased ES versions, instead of combining data
from Version.java and branches.json.
