Subject: [PATCH] fix(azure): external-dns extraArgs must be a list, not a map

The kubernetes-sigs external-dns chart (v1.14.4) expects extraArgs to be
an array of raw flag strings (the chart does `range .Values.extraArgs`
and appends each item to the container args). Passing a map fails the
chart's values.schema.json ("extraArgs: Invalid type. Expected: array,
given: object") and would render the value instead of the flag.

Switch the Azure external-dns values to the list form used elsewhere
(clusters_aws.go), passing the full flag string
`--txt-wildcard-replacement=wildcard`.
