cmake: set c++14 as minimum c++ rev
In this MR we set C++14 as the minimum requirement:
The changes introduced here are:
- Remove the job
ubuntu1604_gcc48
since it defaults tostd=c++1x
and it does not truly support c++14. - Change the job
centos7_gcc48
toCentos7_gcc73
for the same reasons asubuntu1604_gcc48
, it recycles the centos image with the newer GCC 7.3.
