By doing this we delegate the task of finding the correct address family

This patch restores the behaviour of Hostname (previously known as
HostInfo) to always use fqdn. This was broken due to the fact that the
now used getaddrinfo does not return an fqdn in contrast to
gethostbyname_ex().

This patch adds Hostname.GetFqdn() which is always used when
initializing a Hostname object.

A problem this solves is when adding a node and not using its fqdn, node
verify won't complain.

Since this parameter will be used on all daemon startups, it needs to be
available on all nodes. This is achieved by querying it via ssconf. This
patch additionally adds a getter method to readily retrieve the primary
ip family from a ConfigWriter object.

This patch also disables the 'R0904: Too many public methods' pylint
warning, as it crosses the 50 methods limit.

We expose the ip_version (4, 6) to the external interface and internally
we convert it to ip_family (AF_INET=2, AF_INET6=10). This makes the code
more concise as all functions deal with family rather than version.

This patch does not yet expose this parameter via gnt-cluster, but only uses
the constant IP4_VERSION. This will be enabled in a future patch.

These missing changes were initially agreed upon but then forgotten.
First, we move the valid name regex to the class-level such that it
won't be compiled for every invocation of GetIP() and we wrap the result
of getaddrinfo() into a try/except to catch a possible IndexError.

This patch moves the FormatAddress helper function from daemon.py to
netutils.py. This enables its use in http.client as well as in
rapi.client. Furthermore this adds functionality to format IPv6
addresses according to RFC 3986.

It is required for use of literal IPv6 addresses in URLs in pycurl.
For some reason it worked also without the bracketing ("["<address>"]"),
but we do not want to rely on that.

This patch enables IPv6 name resolution by using socket.getaddrinfo
instead of socket.gethostbyname_ex.

It renames the HostInfo class to Hostname and unifies its use throughout
the code. This is achieved by using static calls where no object is
needed and removes some obsolete code.

For now, we just resolve to IPv4 addresses, but this will change once it
is needed.

This patch unifies the netutils functions dealing with IP addresses to
three classes:
- IPAddress: Common IP address functionality
- IPv4Address: IPv4 specific functionality
- IPv6address: IPv6-specific functionality

Furthermore it adds methods to check whether an address is a loopback
address, replacing the .startswith("127") for IPv4 and adding IPv6
support.

It also provides the basis for future IPv6 address handling. Methods to
convert IP strings to their corresponding interger values will allow to
canonicalize IPv6 addresses.
