The supervisor uses the following pattern for async module
initialization
```typescript
// module.ts
export const initialised = (async () => {
// do some async initialization
})();
// somewhere else
import * as module from 'module';
async function setup() {
await module.initialise;
}
```
The above pattern means that whenever the module is imported, the
initialisation procedure will be ran, which is an anti-pattern.
This converts any instance of this pattern into a function
```typescript
export const initialised = _.once(async () => {
// do some async initialization
});
```
And anywhere else on the code it replaces the call with a
```typescript
await module.initialised();
```

This replaces all relative paths in the test suite (e.g
`../src/compose/service.ts`) with the aliased path configured through
tsconfig.
This is a big change but it doesn't affect any functionality
This commit updates all backends that write to /mnt/boot to do it
through a new `lib/host-utils` module. Writes are now done using write +
sync as rename is not an atomic operation in vfat.
The change also applies for writes through the `/v1/host-config`
endpoint.
Finally this change includes some improvements on tests.

This is required as we are phasing out app ids and we need to be able to
get app uuid from the current state of the network. The app-id now
exists as a container in new networks
This commit will restart containers as it needs to recreate the network.
With the move to v3 target state and the move forward to remove
database ids from the supervisor, we want to ensure the ids are only
used for legacy support (such as within the API). This change renames
the method and sets it as deprecated
'mz' can be safely replaced with fs.promises
and util.promisify for faster native methods.
'mkdirp' after Node v8 uses native fs.mkdir, thus
is redundant. 'body-parser' is deprecated and
contained within express v4.x.

This PR adds the following
* Supervisor v1 API application actions now return HTTP status code 423 when locks
are preventing the action to be performed. Previously this resulted in a
503 error
* Supervisor API v2 service actions now returns HTTP status code 423 when locks are
preventing the action to be performed. Previously, this resulted in an
exception logged by the supervisor and the API query timing out
* Supervisor API `/v2/applications/:appId/start-service` now does not
check for a lock. Lock handling in v2 actions is now performed by each
step executor
* `/v1/apps/:appId/start` now queries the target state and uses that
information to execute the start step (as v2 does). Previously start
resulted in `cannot get appId from undefined`
* Extra tests for API methods

This paves the way for running multiple applications and storing
information related to the application against the application itself. A
couple of hacks have been added to v1 and v2 endpoints to maintain
compatability but these should eventually be removed with the addition
of a v3 api.

Each service, when requesting access to the Supervisor API, will
now get an individual key which can be scoped to specific resources.
In this iteration the default scope will be to the application that
the service belongs to.
We also have a `global` scope which is used by the cloud API when in
managed mode.

When reporting device information, send the MAC address of any
interfaces on the system. Also expose in the Supervisor API at
the route GET /v1/device.

We were treating the database class as a singleton, but still having to pass
around the db instance. Now we can simply require the db module and have
access to the database handle.
