generic manifest doesn't work on digital ocean

[andycmaj]

...mainly because of PDNs's requirement for load balancers that support UDP.

apparently, digital ocean LBs don't.

however, i was able to get kubeprod working on DO by

a) creating a new do.jsonnet manifest
b) removing PDS
c) using the digitalocean external-dns provider

this is currently a bit hacky becasuse modifying the generic config autogen shape is not supported by kubeprod's cli.

But actually, using your platform's native DNS routing service actually seems like a better solution anyway whenever possible.

@sameersbn is there any interest among maintainers in supporting DO as a first-class platform?

If so, i'm happy to submit a PR to support this

also happy to provide docs for how to get DO working with generic, but seems like a a bit of a hack without ability to add things (eg, DO API token) to the generic config autogen.json.

PS. here's a GIST with the 2 files needed to accomplish this. note the hardcoded DO token in platform-do.jsonnet:
