[Alexander V. Tikhonov]

gitlab-ci: add Catalina OSX 10.15
    
Added Catalina OSX 10.15 to gitlab-ci testing and removed OSX 10.13,
due to decided to have only 2 last major releases, for now it is
10.14 and 10.15 OSX versions. Also changed the commit job for branches
from 10.14 to 10.15 OSX version.
    
Also added homebrew installation routine as it was suggested in its
instructions. Added installation of the cmake and tool. Added upgrade
of the OSX packages to avoid of fails on already existed packages,
but of the previous versions. Added reinstallation of the python2
with force option to be able to install it to /usr/local/ path to
make pip install there too.
