Incorporate SELinux policy changes introduced in Dogtag 10 in IPA
SELinux policy:
- dogtag10 now runs with pki_tomcat_t context instead of pki_ca_t
- certmonger related rule are now integrated in system policy and
can be removed from IPA policy
Also remove redundant SELinux rules for connection of httpd_t, krb5kdc_t
or named_t to DS socket. The socket has different target type anyway
(dirsrv_var_run_t) and the policy allowing this is already in
system.

Currently, CRL files are being exported to /var/lib/pki-ca
sub-directory, which is then served by httpd to clients. However,
this approach has several disadvantages:
* We depend on pki-ca directory structure and relevant permissions.
If pki-ca changes directory structure or permissions on upgrade,
IPA may break. This is also a root cause of the latest error, where
the pki-ca directory does not have X permission for others and CRL
publishing by httpd breaks.
* Since the directory is not static and is generated during
ipa-server-install, RPM upgrade of IPA packages report errors when
defining SELinux policy for these directories.
Move CRL publish directory to /var/lib/ipa/pki-ca/publish (common for
both dogtag 9 and 10) which is created on RPM upgrade, i.e. SELinux policy
configuration does not report any error. The new CRL publish directory
is used for both new IPA installs and upgrades, where contents of
the directory (CRLs) is first migrated to the new location and then the
actual configuration change is made.

Put the changes from Ade's dogtag 10 patch into namespaced constants in
dogtag.py, which are then referenced in the code.
Make ipaserver.install.CAInstance use the service name specified in the
configuration. Uninstallation, where config is removed before CA uninstall,
also uses the (previously) configured value.
This and Ade's patch address https://fedorahosted.org/freeipa/ticket/2846
Dogtag 10 uses a new installer, new directory layout and new default
ports. This patch changes the ipa install code to integrate these changes.

Certificate renewal can be done only one one CA as the certificates need
to be shared amongst them. certmonger has been trained to communicate
directly with dogtag to perform the renewals. The initial CA installation
is the defacto certificate renewal master.
A copy of the certificate is stored in the IPA LDAP tree in
cn=ca_renewal,cn=ipa,cn=etc,$SUFFIX, the rdn being the nickname of the
certificate, when a certificate is renewed. Only the most current
certificate is stored. It is valid to have no certificates there, it means
that no renewals have taken place.
The clones are configured with a new certmonger CA type that polls this
location in the IPA tree looking for an updated certificate. If one is
not found then certmonger is put into the CA_WORKING state and will poll
every 8 hours until an updated certificate is available.
The RA agent certificate, ipaCert in /etc/httpd/alias, is a special case.
When this certificate is updated we also need to update its entry in
the dogtag tree, adding the updated certificate and telling dogtag which
certificate to use. This is the certificate that lets IPA issue
certificates.
On upgrades we check to see if the certificate tracking is already in
place. If not then we need to determine if this is the master that will
do the renewals or not. This decision is made based on whether it was
the first master installed. It is concievable that this master is no
longer available meaning that none are actually tracking renewal. We
will need to document this.

I couldn't put the dogtag rules into the spec file until we required
dogtag as a component. If it wasn't pre-loaded them the rules loading
would fail because types would be missing.
This policy should really be provided by dogtag. We don't want
to grant read/write access to everything dogtag can handle so we
change the context to cert_t instead. But we have to let dogtag
read/write that too hence this policy.
To top it off we can't load this policy unless dogtag is also loaded
so we insert it in the IPA installer
