update apisnoop image build to work with new apisnoop app structure

[zachmandeville]

APISnoop recently reduced the number of components needed to run, and reorganized its repo to be easier to navigate and maintain.

This PR updates the prow jobs attached to the apisnoop images to reflect both changes. It removes the deprecated hasura, webapp, and postgres images, adds a snoopdb image, and slightly adjusts the build paths.

Hi @zachmandeville. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
