Users may specify dnsu2t config by including a `dns` field
in the `proxy` section of PATCH /v1/device/host-config's body:
```
{
network: {
proxy: {
dns: '1.1.1.1:53',
}
}
}
```
If `dns` is a string, ADDRESS and PORT are required and should be
in the format `ADDRESS:PORT`. The endpoint with error with
code 400 if either ADDRESS or PORT are missing.
`dns` may also be a boolean. If true, defaults will be configured.
If false, the dns configuration will be removed.
If `proxy` is patched to empty, `dns` will be removed regardless
of its current or input configs, as `dns` depends on an active
redsocks proxy to function.

balenaOS v6 enables zstd module compression by default. Add kmod to
runtime-base to support loading of compressed modules.

Before v1, the blinking module would not throw when the passed led file
does not exist. This change checks for file existence and defaults to
`/dev/null` otherwise

The following pattern
```ts
async function longRunning() {
// do something
await setTimeout(delay);
await longRunning();
}
```
Is regularly used for long running operations on the supervisor (e.g.
polling target state). We have
recently discovered that this pattern can slowly leak memory as it
essentially creates an infinite promise chain. Using `void longRunning()` breaks
the chain and avoids the issue.
This commit fixes all those instances where the pattern was used.
Change-type: patch
The balena logging backend now uses async functions to setup the
connection and write messages to the request stream. This adds some
backpressure on `log` calls by by the log monitor module, to prevent a
very agressive container causing the supervisor to waste CPU cycles just
dropping messages.
Change-type: patch
This make the LogBackend `log` method into an async method in
preparation for upcoming changes that will use backpressure from the
connection to delay logging coming from containers.
This also removes unnecessary imageId from the LogMessage type
Change-type: patch
This removes the dependence of the supervisor on the containerLogs
database for remembering the last sent timestamp. This commit instead
uses the supervisor startup time as the initial time for log retrieval.
This might result in some logs missing for services that may start
before the supervisor after a boot, or if the supervisor restarts.
However this seems like an acceptable trade-off as the current
implementation seems to make things worst in resource contrained
environments.
We'll move storing the last sent timestamp to a better storage medium in
a future commit.
