* Add .gitlab-ci.yml * Use | instead of > for multiline commands This honor new-lines and makes ; unnecessary * Use ubuntu:bionic as base image * Move cache initialization before apt-get installs * Cache apt packages * Move installation of wget and unzip up as we need it for the cache * Prevent apt from deleting caches * Collect test logs into artifact * Make combine_logs.py always look for the template in the correct dir * Move final cache stuff into after_script * Reintroduce PYTHON_DEBUG=1, but only for .travis.yml * Install jinja2 in Travis builder image * Enable ChainLocks after quorums have been created Creating 4 quorums causes a lot of blocks to be created and signed by ChainLocks, which then causes timeouts later. * Increase timeout in wallet-dump.py test The first dumpwallet is quite slow sometimes, which then makes the later called dumpwallet throw a wallet locked exception.
