resource_limits: Delete settings for httpd

Delete settings in resource_limits.conf that are no longer used.  In
particular, commit 3b74dd3d162a9a3b63a7ac4e1eaccea6b889e186 (removing v1
cartridges) removed all use of the apache_bandwidth, apache_maxconnection,
apache_bandwidtherror, rotatelogs_interval, and rotatelogs_format settings.

Note that the tc_max_bandwidth and tc_user_share settings can be used
now for bandwidth control.

oo-admin-ctl-iptables-port-proxy: SELinux fix

Give input to iptables-restore on standard input instead of using command
substitution.

Bash was expanding the <(...) command-substitution to a fifo, which
oo-admin-ctl-iptables-port-proxy was then passing to the iptables-restore
command as a command-line argument.  If oo-admin-ctl-iptables-port-proxy
was being run from the /etc/init.d/openshift-iptables-port-proxy
initscript, then Bash would have an SELinux context with type initrc_t, and
it thus would create the fifo also with type initrc_t.  However,
iptables-restore transitions SELinux contexts so that it is running with
the iptables_t type.  The iptables-restore command would thus fail when it
tried to open the fifo because SELinux policy blocks processes with type
iptables_t from reading fifos with type initrc_t.

(Interestingly, the manpage for iptables-restore does not indicate that
iptables-restore is even supposed to take a filename as an argument.)

This commit fixes bug 1020391.
