Subject: [PATCH v1] Add GitLab CI to PostgreSQL

Create a GitLab CI file that builds PostgreSQL on multiple systems.
Run Meson test on compiled binaries. As Meson was introduced recently in
master branch, only run Meson build stage if a meson.build file exists
which allows this CI to work on other release branches.
REL_11_STABLE through REL_15_STABLE have been tested.

+# This Gitlab-CI pipeline offers basic validation that a commit did not
+# introduce easily detectable regressions. Builds run primairly on a new Fedora,
+# which has all the latest upstream build dependencies and thus is the primary
+# testing target, as eventually everything in Fedora becomes the next CentOS and
+# Red Hat releases.
+#
+# In addition test building on CentOS 7 and 8 to ensure that the code base
+# remains reasonably backwards compatible.
