### Other
- #5751: @josegonzalez Update all golang dependencies to fix go.0 tests
This was necessary on Ubuntu 14.04 (and maybe 16.04) due to using a version of Dokku older than #2699, so we can safely drop the support here as we haven't supported either in a few years.
This change allows us to have an integration branch for each release that contains tested changes for each minor. Rather than have to block merging until a minor is ready for release - and subsequently have to deal with constant rebase issues - we will now have an integration branch per-release. This will be the target for minor-related changes - mostly new features, but also refactors and bc-breaks - while the trunk branch will stay safe for merging patch changes.
Note that we'll still need to rebase the integration branch every so often, but at least this allows us to avoid many long-running MRs.
Rather than always delete the image, we will now check if the alt image tag is equivalent to the source-image specified by the git:from-image command. If it is, we will ignore deletion.
Closes#5702
Since there's no instruction for how to use the DOKKU_LETSENCRYPT_EMAIL env variable, I'm not sure why it's included here.
So, instead, I'm proposing to include the step for directly setting the global email for `dokku-letsencrypt`.
(It'll be nice to also get some explanation behind creating that env variable)
