oo-iptables-port-proxy: Rewrite getaddr

Clean up the getaddr command to use pure Bash with only one fork and
simpler (and hopefully more reliable) parsing.
oo-iptables-port-proxy: getaddr: check ipaddr

Check that ipaddr is not empty in getaddr and report a helpful error
message if it is.

This commit fixes bug 1121200.
Fix frontend system_proxy_delete/system_proxy_set

OpenShift::Runtime::FrontendProxyServer#system_proxy_delete and
OpenShift::Runtime::FrontendProxyServer#system_proxy_set: Return values in
a consistent ordering (stdout, stderr, exit status) irrespective of whether
arguments were passed.

Previously, these methods returned the exit status as the first value
instead of the last if no arguments were provided.

Fix the corresponding test cases to expect the correct ordering.

This commit fixes bug 1121238.
