Add epel-rpm-macros for CentOS/RHEL install-dep
%py2_install is required by vpp-api-python and is not available on bare CentOS/RHEL install, causing 'fg: no job control' error. Added 'epel-rpm-macros' to the list of EPEL dependencies Change-Id: I1e09d7d825d9d8db06e7385d2b8d5579c8ce748b Signed-off-by: Alexander Popovsky (apopovsk) <apopovsk@cisco.com>
