93d080d726 destroy httpd ccache after stopping the service
This will force recreation of the file-based ccache after IPA restore and
prevent a mismatch between cached and restored Kerberos keys.

495da412f1 Provide Kerberos over HTTP (MS-KKDCP)
Add integration of python-kdcproxy into FreeIPA to support the MS
Kerberos KDC proxy protocol (MS-KKDCP), to allow KDC and KPASSWD
client requests over HTTP and HTTPS.

- freeipa-server now depends on python-kdcproxy >= 0.3. All kdcproxy
  dependencies are already satisfied.
- The service's state is configured in cn=KDC,cn=$FQDN,cn=masters,cn=ipa,
  cn=etc,$SUFFIX. It's enabled, when ipaConfigString=kdcProxyEnabled is
  present.
- The installers and update create a new Apache config file
  /etc/ipa/kdcproxy/ipa-kdc-proxy.conf that mounts a WSGI app on
  /KdcProxy. The app is run inside its own WSGI daemon group with
  a different uid and gid than the webui.
- A ExecStartPre script in httpd.service symlinks the config file to
  /etc/httpd/conf.d/ iff ipaConfigString=kdcProxyEnabled is present.
- The httpd.service also sets KDCPROXY_CONFIG=/etc/ipa/kdcproxy.conf,
  so that an existing config is not used. SetEnv from Apache config does
  not work here, because it doesn't set an OS env var.
- python-kdcproxy is configured to *not* use DNS SRV lookups. The
  location of KDC and KPASSWD servers are read from /etc/krb5.conf.
- The state of the service can be modified with two ldif files for
  ipa-ldap-updater. No CLI script is offered yet.

7ff7b1f533 move IPA-related http runtime directories to common subdirectory
When both 'mod_auth_kerb' and 'mod_auth_gssapi' are installed at the same
time, they use common directory for storing Apache ccache file. Uninstallation
of 'mod_auth_kerb' removes this directory leading to invalid CCache path for
httpd and authentication failure.

Using an IPA-specific directory for credential storage during apache runtime
avoids this issue.

9a1a409d63 provide dedicated ccache file for httpd
httpd service stores Kerberos credentials in kernel keyring which gets
destroyed and recreated during service install/upgrade, causing problems when
the process is run under SELinux context other than 'unconfined_t'. This patch
enables HTTPInstance to set up a dedicated CCache file for Apache to store
credentials.
