`common.TouchFile` opened files with `O_TRUNC`, so the call from `common.SshTask.Execute` against `~/.ssh/known_hosts` emptied the dokku user's previously trusted host keys before `goph.DefaultKnownHosts()` read them. Running `scheduler-k3s:cluster:add` without `--insecure-allow-unknown-hosts` then failed with `knownhosts: key is unknown` and left a zero-byte `known_hosts`. The function now matches `touch(1)` semantics: create the file if missing, otherwise leave its contents intact.
This standardizes the extraction code and makes it easier to reuse in future implementations of file extraction.
Additionally, this adds a way to extract folders from codebases.
The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit
replaces the existing io/ioutil functions with their new definitions in
io and os packages.

This change also moves the referenced Procfile out to a host path once on deploy vs potentially several times, which should speed up deploys a small amount and simplify reasoning about the file.
Closes#5112
We will no longer support CentOS, Fedora, and Opensuse as installation targets. These are not actively maintained by anyone with commit rights and occasionally cause issues for users as they are not tested during the release process.
Rather than have subpar support for an untested operating system, we're removing support for them completely. Users of these operating systems should take a look migration to the docker-based installation method, which will always be tested and supported by the project.
Additionally, drop support for Debian 9 as it is now EOL.
RHEL blocks users from executing crontab as themselves Because Of Reasons so we need to use sudo instead.
Also refactors file writing to properly support writing the permissions on sudoers files going forward.
Closes#5020
