Add CentOS 8 support * Add "centos" element, a CentOS version-independent element. This is in line with the same work done for RHEL in Stein cycle. * Deprecate the centos7 element. CentOS 7 support itself it not deprecated though. The new "centos" element provides the same support level as the "centos7" element. * Add functional testing The default CentOS version is 8. You can adjust it using the DIB_RELEASE environment variable. Change-Id: I373ba2296c4613765676e59aabd9c651345298d1 2019-09-24 10:46:12 +00:00			`#!/bin/bash`

Support non-x86_64 DIB_DISTRIBUTION_MIRROR variable for CentOS 7 Other architectures are stored under "altarch" for CentOS 7, update the match. Convert the delimiters to "," to avoid a subtle problem with "\|" -- POSIX states Within the BRE and the replacement, the BRE delimiter itself can be used as a literal character if it is preceded by a backslash. So "s\|\(foo\\|bar\)\|moo\|" doesn't do what you might think; the inner pipe becomes a literal \| and this will not match "foo" or "bar".
