Do not install mysql if mariadb is installed on openSUSE

mariadb and mysql are conflicting on a package level, but are compatible
for our needs. So if mariadb is already installed, do not try to install
mysql.

xenapi: cleanup VM Installation

VM installation created a machine with multiple network interfaces. This
is a needless complexity at that point, we only need one interface. This
change removes the complex network interface setup from
install-os-vpx.sh script, so that only one network interface is created,
which is connected to the selected network (management by default). This
change also removes a lot of non-used code from install-os-vpx.sh
Specify the network to be used for ubuntu netinstall with:

    UBUNTU_INST_BRIDGE_OR_NET_NAME

defaults to $MGT_BRIDGE_OR_NET_NAME.

This change also includes:
 - use precise as default

The URLs advertised in the data returned by keystone's '/' route default

the Qpid clients need the hostname of the potentially

communication between components.

Add variable to specify additional parameters for the Neutron service.

This patch adds a new variable, Q_SRV_EXTRA_DEFAULT_OPTS, which can
override any parameter of the [DEFAULT] section of the neutron.conf
file. It can be used for example to define the number of DHCP agents
that should host a network:
  Q_SRV_EXTRA_DEFAULT_OPTS=(dhcp_agents_per_network=2)
