Add Dispatch Solo OVA release pipeline (#725)

Pipeline tracks version and triggers e2e tests for every version bump.
Revision that passes tests is then used to build an OVA. OVA is stored
on an S3 bucket. There is also a Github release created for that
version.

Also changes the API e2e tests to use default  timeout and retry values
(previous values were too low and caused tests failures despite the
gateway functioning correctly)

* API cache now works across restarts of dispatch server
