Fail gracefully if the supplied hostname isn't fully-qualified in
ipa-server-install.

A dogtag replica file is created as usual. When the replica is installed
dogtag is optional and not installed by default. Adding the --setup-ca
option will configure it when the replica is installed.

A new tool ipa-ca-install will configure dogtag if it wasn't configured
when the replica was initially installed.

This moves a fair bit of code out of ipa-replica-install into
installutils and cainstance to avoid duplication.

The hostname is passed in during the server installation. We should use
this hostname for the resulting server as well. It was being discarded
and we always used the system hostname value.

Important changes:
- configure ipa_hostname in sssd on masters
- set PKI_HOSTNAME so the hostname is passed to dogtag installer
- set the hostname when doing ldapi binds

This also reorders some things in the dogtag installer to eliminate an
unnecessary restart. We were restarting the service twice in a row with
very little time in between and this could result in a slew of reported
errors, though the server installed ok.

Make sure that IPA can be installed with root umask set to secure
value 077. ipa-server-install was failing in DS configuration phase
when dirsrv tried to read boot.ldif created during installation.

For the most part certificates will be treated as being in DER format.
When we load a certificate we will generally accept it in any format but
will convert it to DER before proceeding in normalize_certificate().

This also re-arranges a bit of code to pull some certificate-specific
functions out of ipalib/plugins/service.py into ipalib/x509.py.

This also tries to use variable names to indicate what format the certificate
is in at any given point:

dercert: DER
cert: PEM
nsscert: a python-nss Certificate object
rawcert: unknown format

Compare the configured interfaces with the supplied IP address and
optional netmask to determine if the interface is available.

https://fedorahosted.org/freeipa/ticket/1175

Implements a way to pass match_local and parse_netmask parameters
to IP option checker.

Now, there is just one common option type "ip" with new optional
attributes "ip_local" and "ip_netmask" which can be used to
pass IP address validation parameters.

Port 9443 (Agent secure port on PKI-CA) was missing. Additionaly,
checked port descriptions case consistency fixed.

When a new DNS zone is being created a local hostname is set as a
nameserver of the new zone. However, when the zone is created
during ipa-replica-prepare, the the current master/replica doesn't
have to be an IPA server with DNS support. This would lead to DNS
zones with incorrect NS records as they wouldn't point to a valid
name server.

Now, a list of all master servers with DNS support is retrieved
during DNS zone creation and added as NS records for a new DNS
zone.

The conditional used to determine if thd CA 389-ds instance was already
configured was rather poor so it was possible to pass command-line
arguments in to confuse it. This would cause it to not be installed at
all causing the dogtag installation to fail in a strange way.
