Happy-eyeballs performs [dns lookups](https://github.com/balena-io-modules/happy-eyeballs/blob/master/src/happy-eyeballs.ts#L23)
for the requested addresses, however, because of the order of imports it
was not using the supervisor custom `dns.lookup` that handles `.local`
name resolution, making address resolution fail in those cases.
Moving the import after the `dns.lookup` patch fixes the problem.
The supervisor performs its own local resolution for `.local`
addresses due to a limitation in [musl](https://wiki.musl-libc.org/future-ideas.html).
The resolution function was not following exactly the nodejs [dns.lookup
specification](https://nodejs.org/api/dns.html#dnslookuphostname-options-callback)
which could cause certain clients to fail (in this case happy-eyeballs). This
updates the function to follow the specification.

This avoids the supervisor trying to get back to the preloaded target
state if the database is deleted by any reason. It does this by moving the
used apps.json to a backup location.

Depends-on: #1841
The supervisor always applies target state on start to ensure that the
device is at the correct in case of a crash or another reason. This had
the side effect that if the database is deleted, the supervisor would
apply target state (which is empty), stopping services and possibly
causing volume data loss.
This prevents that behavior and ensures that the supervisor only
applies target state if a target has been set either by the cloud, preload or local
mode.

PR #1824 changed app update behavior to test that all images are there
before moving between releases. This check always fails in local mode
since local mode images are handled differently.
This PR fixes local mode again by skipping the check when `localMode` is
set.
Change-type: patch
The strategy has been broken for a while but it was not clear how to
fix it before the changes to image management. This PR fixes application
manager to remove images before downloading the new image. This will
only have an effect on changing images.
Closes: #1233
