No longer installs pcre2, which is built from source later on.
CMake is only installed if a recent version (3.16) is not found.
Jansson install cannot be removed yet as the Avro build requires
it.
VM should have 8 cores to make build faster in GCloud.
To get rid of ssfs between build hosts the build step
and upgrade test step are separated as well as
repository discriåtion generation

GCloud machines has more strict access rights settings. Derect calls of
'chmod' are needed to make all configuration files (e.g. 'fwf/rules') be
accessable by Maxscale.
We do not build RHEL packageas, but create RHEL repos as symlinks
to CentOS repos. For RHEL8 was an expection intruduced, because
CentOS 8 was not available at the time when RHEL8 was released.
Now CentOS 8 is also available, switching to CentOS 8 image.
In CentOS8 some -devel packages are moved to PowerTools repository which
is disabled by default. install_build_depends now checks if this repo
is in the repolist then add enablerepo=PowerTools to the yum command
Installation of Docker is removed from build script because it is done
in the not very reliable way and can fail and cause build failure.
E.g. this installation causes conflict with existing Docker.
Checking presence of 'apt', 'yum' or 'zypper' command is not very
reliable way to determine package manager type.
E.g. OpenSUSE 25 has 'apt' which is wrapper over 'zypper' or rpm tools
can be installed on Ubuntu.
More relible way is to check /etc/*-release file and if it is not
availabe try to check presence of apt, yum or zypper
During the build first binary packages are generated and copied into
'pre-repo' direcotory. Then binary repository is created and next
step is to copy repository into final directory according agreed
binary repo sirectories structure. After it temparal direcotries
are not needed.
Now Docker is installed to VM which are used to build Maxscale. It allows to run tests which require Docker without installing it
during build process.
