Moving WS-security policies from keys directory

Moving ??-client-policy.xml files (generated at build time),
from /var/lib/eucalyptus/keys, where they often get clobbered
by careless (re)generation of keys, to /usr/share/eucalyptus/policies

Fixes EUCA-8706

Moving httpd-??.conf files into run dir

Moving httpd-[nc]c.conf files, generated by init scripts,
into /var/run/eucalyptus directory. Also, eschewing the
temporary httpd-tmp.conf file, which isn't necessary.

Fixes EUCA-9558
