Fixes broken L4 ExternalName services.
Details
---------
The `tcp_udp_balancer.lua` script checks if the property
`backend.service.spec["type"]` equals "ExternalName". If so,
the script does a DNS lookup on the name in order to configure
the backend configuration.
However, before this commit, the k8s `Service` data was
_not_ set on the `Backend` struct passed into the `tcp_udp_balancer.lua`
script and therefore the ExternalName check always returned false.
This commit fixes the issue by setting the `Service` field on
the `Backend` struct. This also requires adding a new field to the
`L4Backend` struct first, so that it's available to set on the `Backend`.

When serving many hosts from one nginx, the metrics may become too
numerous for Prometheus. Add a flag to disable the host label, so
that metrics are totalled across all hosts.
Adds the ability to create alternative backends. Alternative backends enable
traffic shaping by sharing a single location but routing to different
backends depending on the TrafficShapingPolicy defined by AlternativeBackends.
When the list of upstreams and servers are retrieved, we then call
mergeAlternativeBackends which iterates through the paths of every ingress
and checks if the backend supporting the path is a AlternativeBackend. If
so, we then iterate through the map of servers and find the real backend
that the AlternativeBackend should fall under. Once found, the
AlternativeBackend is embedded in the list of VirtualBackends for the real
backend.
If no matching real backend for a AlternativeBackend is found, then the
AlternativeBackend is deleted as it cannot be backed by any server.
