The ``ipa-client-install`` command now supports PKINIT for client
enrollment. Existing X.509 client certificates can be used to
authenticate a host.
Also restart KRB5 KDC during ``ipa-certupdate`` so KDC picks up new CA
certificates for PKINIT.
*Requirements*
- The KDC must trust the CA chain of the client certificate.
- The client must be able to verify the KDC's PKINIT cert.
- The host entry must exist. This limitation may be removed in the
future.
- A certmap rule must match the host certificate and map it to a single
host entry.
*Example*
```
ipa-client-install \
--pkinit-identity=FILE:/path/to/cert.pem,/path/to/key.pem \
--pkinit-anchor=/path/to/kdc-ca-bundle.pem
```
