ci-scripts 3.2 release: support for GitLab CI/CD

[Ralph Lange via Tech-talk <tech-talk@aps.anl.gov>]

Release 3.2 of the ci-scripts module is available on GitHub.

https://github.com/epics-base/ci-scripts/releases

This release adds full support of GitLab CI/CD as a CI service:

• Docker-based runners on Linux (on VM instance per job)
• Can use any Docker image from Dockerhub (the examples use ubuntu:bionic)
• Compile natively on Linux (gcc, clang)
• Cross-compile for Windows 32bit and 64bit using MinGW and WINE
  
• Cross-compile for RTEMS 4.9 and 4.10 (Base >= 3.15)
• Build-dependencies are cached (for faster builds).

As always: thanks a lot to all contributors and testers!

Please report all issues on the GitHub tracker.

See you at the EPICS Collaboration meeting,
~Ralph
