[openstack][octavia] Override default 50000 OctaviaTimeoutMemberData

Hi Folks, We're using charmed openstack and charmed k8s on top of that. In our k8s environment, we have an nginx ingress controller that uses the openstack-integrator charm to create and manage octavia LBs. I'm trying to figure out how to manage the haproxy frontend and backend timeout parameters that seem to default to 50000ms via: OctaviaTimeoutClientData OctaviaTimeoutMemberData Ideally, being able to specify this in the k8s service manifest that gets passed down into the octavia config would be "the way." Any ideas? Thanks! -- Andy Speagle
