The attached patch addresses the following PKI issues:
* TRAC Ticket #395 - Dogtag 10: Add a Tomcat 7 runtime requirement to
'pki-server'
* TRAC Ticket #398 - Move default location for client certificate database
Note that this implementation of ticket #398 chose a slightly different
default for the client directory path,
"~/.pki/<pki_instance_id>_<pki_subsystem>" rather than the suggested
"~/.pki/certs/<instance>", so that the existing option to purge the
client directory could still be used as is to completely remove this
entire directory structure.
