In version 2.0.15 `gotify` switched to `packr` at 2.x which is why the
UI can't be served properly via HTTP and causes an empty 500 response and
the following errors in `journald`:
```
2020/09/12 19:18:33 [Recovery] 2020/09/12 - 19:18:33 panic recovered:
GET / HTTP/1.1
Host: localhost:8080
Accept: */*
User-Agent: curl/7.72.0
stat /home/ma27/Projects/ui/build/index.html: no such file or directory
```
This wasn't caught by the VM-test as it only tested the REST and push
APIs. Using their internal `packr.go` script in our build as it's the
case in the upstream build-system[1] fixes the issue.

ecb73fd555 introduced a new keepVmState
CLI flag for test-driver.py. This CLI flags gets forwarded to the
Machine class through create_machine.
It created a regression for the boot tests where __main__ end up not
being evaluated. See
https://github.com/NixOS/nixpkgs/pull/97346#issuecomment-690951837 for
bug report.
Defaulting keepVmState to false when __main__ ends up not being
evaluated.
This reverts commit 42eebd7ade, reversing
changes made to b169bfc9e2.
This breaks nfs3.simple test and even current PR #97656 wouldn't fix it.
Therefore let's revert for now to unblock the channels.
This is a temporary fix for #97433. A more proper fix has been
implemented upstream in systemd/systemd#17001, however until it gets
backported, we are stuck with ignoring the error.
After the backport lands, this commit should be reverted.
`rngd` seems to be the root cause for slow boot issues, and its functionality is
redundant since kernel v3.17 (2014), which introduced a `krngd` task (in kernel
space) that takes care of pulling in data from hardware RNGs:

Closes: #96067
This commit fixes the ejabberd tests for hydra:
mod_http_upload and mod_disco need to be explicitly enabled, and a
handler needs to be setup to make it work. Also, the client needs to be
able to contact the server.
The commit also fixes the situation where http upload failed: in that
case the client would wait forever because nothing catched the error.
Finally, there remains a non-reproducible error where ejabberd server
fails to start with an error like:
format: "Failed to create cookie file '/var/lib/ejabberd/.erlang.cookie': eacces"
(happens ~15%) I tried to check existence of /var/lib/ejabberd/ in
pre-start script and saw nothing that would explain this error, so I
gave up about this error in particular.
