For each ingress controller, the format of ingress host,
path and annotations are different. To support different
kinds of controller, this PR adds new ingress config field
to http trigger spec. A user can set annotations, host and
path based on the type of underlying ingress controller
with CLI.
Command example:
fission route create --name foo \
--url /foo/{bar} --function foofn --createingress \
--ingressannotation "nginx.ingress.kubernetes.io/ssl-redirect=false" \
--ingressannotation "nginx.ingress.kubernetes.io/use-regex=true" \
--ingressrule "*=/foo/*"
