[Tarantool-patches] [PATCH v3] Add CentOS 8 image dockerfile

["Alexander V. Tikhonov" <avtikhon@tarantool.org>]

Added CentOS 8 image named as el-8 with the following differences from
CentOS 7:
(check https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/considerations_in_adopting_rhel_8/index )
 - added PowerTools repository as suggested at
   https://fedoraproject.org/wiki/EPEL
 - at CentOS 8 the localization environment changed to "C";
 - removed curl which is allready installed at the parent image
   (needed by backport repository);
 - changed pygpgme to python3-gpg which was removed at CentOS 8 (check A.3.
   "Removed packages part") (needed by backport repository);
 - saved backport repository due to python2 still in use while CentOS 8
   changed its packages to python3 and we need to backport python-gevent
   package;
 - cmake28 and cmake3 removed due to CentOS 8 installs 3.11 version;
 - removed devtoolset and scl* repositories due to devtoolset-8 is
   already in the standard repositories and scl* repositories still
   not available.
