From [https://github.com/appc/spec/blob/master/spec/aci.md](https://github.com/appc/spec/blob/master/spec/aci.md):
>environment (list of objects, optional) represents the app's environment variables (ACE can append). The listed objects must have two key-value pairs: name and value. The name must consist solely of letters, digits, and underscores '_' as outlined in IEEE Std 1003.1-2008, 2016 Edition, with practical considerations dictating that the name may also include periods '.' and hyphens '-'. The value is an arbitrary string. These values are not evaluated in any way, and no substitutions are made.
Dotted environment variables are frequently used as a part of the Spring Boot pattern. (re: ZD-6116)
This PR specifically doesn't address the conversion of hyphens (`-`) due to an issue with rkt [[Nomad GH # 2358]](https://github.com/hashicorp/nomad/issues/2358).
1. Extra whitespace
2. Remove redundant code
3. Remove redundant markup from test
4. placement-failure should be used as an inline component
5. Prefer `assign` polyfill
6. Use new `@ember' org style imports
If there are any errors in container setup after c.Create() in
Start(), the container will be left around, with no way to clean it up
because the handle will not be created or returned from Start.
Added a wrapper that checks for errors and performs appropriate
cleanup. Returning a cleanup function from a wrapped function instead
of just doing the cleanup before returning the error helps to ensure
that future changes that might add or change error exits can't forget
to consider a cleanup function.
Adds a check to the invalid config test case to check that a container
created with an invalid config doesn't get left behind.

Related to #3681
If a user specifies an invalid port *label* when using
address_mode=driver they'll get an error message about the label being
an invalid number which is very confusing.
I also added a bunch of testing around Service.AddressMode validation
since I was concerned by the linked issue that there were cases I was
missing. Unfortunately when address_mode=driver is used there's only so
much validation that can be done as structs/structs.go validation never
peeks into the driver config which would be needed to verify the port
labels/map.
Fixes#3681
When in drive address mode Nomad should always advertise the driver's IP
in Consul even when no network exists. This matches the 0.6 behavior.
When in host address mode Nomad advertises the alloc's network's IP if
one exists. Otherwise it lets Consul determine the IP.
I also added some much needed logging around Docker's network discovery.
Allow lxc driver to accept bind mount config similarly to the docker
driver.
Includes some static sanity checks in Validate step
