option to expose graphql api + visualizer with ingress

[tuananh]

so that we can use it for visualizer.

currently, it's set to this one:

helm-charts/charts/guac/templates/guac-cm.yaml

Line 26 in 9f53560

gql-addr: http://{{ $.Values.guac.graphqlServer.name }}.{{ $.Release.Namespace }}.svc.cluster.local:{{ .targetPort }}/query

which is not accessible by visualizer

Pending review and merge of guacsec/guac-visualizer#23, which will allow graphql api endpoint to be configurable.

@sunnyyip is this issue closed?

Not yet, now that we put a proxy in front of the visualizer to workaround how it finds the gql server, we can create ingress as the subject suggests.
