**What**
- Use the compose-go library to read the service definitions from an
external compose file instead of building them in Go
- Add default compose file and copy during `faasd install`
- Add test for load and parse of compose file
- Make testing easier by sorting the env keys
- Allow append to instantiate the slices so that we can more easily test
for proper parsing (e.g. nil is still nil etc)
- Add the arch suffix to the compose file and set this as part of the
env when we parse the compose file. This allows faasd to dynamically
set the arch suffix used for the basic auth and the gateway images.

This patch fixes a vulnerability in the secrets API, however
it is important to stress that the user must be authenticated
as the admin user on the REST API before they can attempt this.
Reported by Appsecco via email. @lucasroesler, Appsecco and
myself believe this to be of low severity.
The fix prevents directory traversal characters from being
used in secret names. If a secret name such as:
../../root/.ssh/authorized_keys were to be used, an attacker
could remove the value and write their own.
Tested with unit tests and tests are now made to run
via the CI and a new Makefile target.

**What**
- Instead of sleeping to ensure the msg channel is populated, use an
unbuffered channel. This seems to work just as well in all the manual
tests cases
Signed-off-by: Lucas Roesler <roesler.lucas@gmail.com>
**What**
- Remove the `output-fields` flag because not all journalctl versions
support it
- Add a short sleep to the start of the log stream to avoid some kind of
race/buffering condition with the Handler
Signed-off-by: Lucas Roesler <roesler.lucas@gmail.com>
**What**
- journald log provider using exec to journalctl
```
journalctl -t <namespace>:<name> --output=json --since=<timestamp> <--follow> --output-fields=SYSLOG_IDENTIFIER,MESSAGE,_PID,_SOURCE_REALTIME_TIMESTAMP
```
- This can be tested manually using `faas-cli logs` as normal, e.g.
`faas-cli logs nodeinfo` should tail the last 5 mins of logs.
- Very basic tests ensuring that the `journalctl` comamand is correctly
construction and that the json log entrys are parsed correctly.
- Add simple e2e test to grep the function logs

The behaviour prior to this patch caused some confusion for
users since they expected a behaviour like Swarm / Kubernetes
which always pulls images by default, even if cached. I've tested
the change and it is working as expected. By default images are
always pulled upon deployment.
To revert to the prior behaviour, simply add to faasd up:
--pull-policy=IfNotPresent

The collect command redirects function logs to the journal for
viewing on journalctl. faas-cli logs is not implemented as of
yet. View logs with journalctl -t openfaas-fn:FN_NAME_HERE.
Tested on Dell XPS with Ubuntu Linux. The approach takes
inspiration from the Stellar project.

The use of containerd and CNI functions has been refactored to reuse

This appeared to prevent the provider's secret code from
creating files in its working directory. The patch makes all
code use the same permission.

Adds secrets support and binding of secrets at runtime to
functions. Files are written in plain-text to a 0644 permission
folder which can only be read by root and the containers
requesting the secret through the OpenFaaS API.
Tested by deploying an alpine function using "cat" as its
fprocess.
Happy to revisit at a later date and look into encryption at
rest. This should be on-par with using Kubernetes in its
default unencrypted state.

Fixes a bug when attempting to access a non-existant IP from

Renames the provider from faas-containerd
Updates function deletion grace period to 30s to prevent any
errors in the REST API during a long-running deletion.
Tested on Linux with the figlet function which by default takes
around 5s to delete due to its write_timeout value, the deletion
now blocks rather than throwing an error.

This patch completes part of the work in #20 by porting the code
for faas-containerd in-tree. When tested, I was able to deploy
and then remove figlet from the store on `x86_64`.
In a follow-up PR, duplication will be removed where possible
and consolidated with updated documentation.

* Issue was detected whilst testing 0.4.0 from @Waterdrips which
added basic auth, but the header was not being propagated.
* This code is tested in OpenFaaS already, but unit tests will
be added retrospectively.
* Proxy now reads the gateway URL via a channel instead of from
a file to make unit testing easier.
Basic auth now works as expected with faas-cli login / list.
