Several optimizations have been done to the pipelines, to make them
closer to what can be reproduced, with the existing scripts, in a
development environment:
- Use start.sh and build.sh scripts to build and start containers
- Use variables to configure different stages instead of using separate
files
- Use a commom 'prepare_environment' to create the environment for every
pipeline
- Use a single file defining testing steps (run_tests.yml)
- Remove Centos 7 pipelines
- Reduce the number of pipelines in the test matrix due to the amount of
time that tests were using
- Use Azure "loop" (each) to create test groups
The above changes make the pipelines easier to understand and modify.
