/**
* enableVlanNetwork creates a Network object, Vlan object, and thereby a
* tagged PIF object in Xapi.
*
* In XenServer, VLAN is added by - Create a network, which is unique
* cluster wide. - Find the PIF that you want to create the VLAN on. -
* Create a VLAN using the network and the PIF. As a result of this
* operation, a tagged PIF object is also created.
*
* Here is a list of problems with clustered Xapi implementation that we are
* trying to circumvent. - There can be multiple Networks with the same
* name-label so searching using name-label is not unique. - There are no
* other ways to search for Networks other than listing all of them which is
* not efficient in our implementation because we can have over 4000 VLAN
* networks. - In a clustered situation, it's possible for both hosts to
* detect that the Network is missing and both creates it. This causes a lot
* of problems as one host may be using one Network and another may be using
* a different network for their VMs. This causes problems in migration
* because the VMs are logically attached to different networks in Xapi's
* database but in reality, they are attached to the same network.
*
* To work around these problems, we do the following.
*
* - When creating the VLAN network, we name it as VLAN-UUID of the Network
* it is created on-VLAN Tag. Because VLAN tags is unique with one
* particular network, this is a unique name-label to quickly retrieve the
* the VLAN network with when we need it again. - When we create the VLAN
* network, we add a timestamp and a random number as a tag into the
* network. Then instead of creating VLAN on that network, we actually
* retrieve the Network again and this time uses the VLAN network with
* lowest timestamp or lowest random number as the VLAN network. This allows
* VLAN creation to happen on multiple hosts concurrently but even if two
* VLAN networks were created with the same name, only one of them is used.
*
* One cavaet about this approach is that it relies on the timestamp to be
* relatively accurate among different hosts.
*
* @param conn
* Xapi Connection
* @param tag
* VLAN tag
* @param network
* network on this host to create the VLAN on.
* @return VLAN Network created.

* the description on that method.
*
* In order to understand this, we have to see what type of networks are
* within a XenServer that's under CloudStack control.
*
* - Native Networks: these are networks that are untagged on the XenServer
* and are used to crate VLAN networks on. These are created by the user and
* is assumed to be one per cluster. - VLAN Networks: these are dynamically
* created by CloudStack and can have problems with duplicated names. -
* LinkLocal Networks: these are dynamically created by CloudStack and can
* also have problems with duplicated names but these don't have actual
* PIFs.
*
* In order to speed to retrieval of a network, we do the following: - We
* retrieve by the name. If only one network is retrieved, we assume we
* retrieved the right network. - If more than one network is retrieved, we
* check to see which one has the pif for the local host and use that. - If
* a pif is not found, then we look at the tags and find the one with the
* lowest timestamp. (See enableVlanNetwork())
*
* @param conn
* Xapi connection
* @param name
* name of the network
* @return XsNic an object that contains network, network record, pif, and
* pif record.
* @throws XenAPIException
* @throws XmlRpcException
