Simplified scripts for copying to jb-main (#1407)

Now we need only to switch to the commit, and call a needed script. It
creates 2 branches, which can be tested on CI, and merged with simple
git merge.

Branches:

+The purposes of these scripts is to copy some subfolder to jb-main branch from "integration" or "integration-release/*".
+
+1. Checkout the commit you want to copy ("integration" or "integration-release/*")
+
+2. Merge jb-main to integration, pick "jb-main" state in a case of conflicts in other folders
+
+3. Call `./copyCompose.sh` (use another script for another folder)
+
+It creates 2 branches:
+- integration-copy/$hash/to-jb-main - should be merged to "jb-main". It is based on merge-base(currentCommit, jb-main) and has the copy of the subfolder from currentCommit
+- integration-copy/$hash/to-integration - should be merged to "integration", to avoid conflicts in future merges of jb-main. It is created as "empty" merge of "to-jb-main" to merge-base(currentCommit, integration)
