2. Added tests to check both cases.
3. Updated docs.

In case some ingress have a syntax error in the snippet configuration,
the freshly generated configuration will not be reloaded to prevent tearing down existing rules.
Although, once inserted, this configuration is preventing from any other valid configuration to be inserted as it remains in the ingresses of the cluster.
To solve this problem, implement an optional validation webhook that simulates the addition of the ingress to be added together with the rest of ingresses.
In case the generated configuration is not validated by nginx, deny the insertion of the ingress.
In case certificates are mounted using kubernetes secrets, when those
changes, keys are automatically updated in the container volume, and the
controller reloads it using the filewatcher.

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`.
