Audit details
* Audit logs and broadcasts accept `details` whose values are included as log tags and MRSK_* env vars passed to the broadcast command
* Commands may return execution options to the CLI in their args list
* Introduce `mrsk broadcast` helper for sending audit broadcasts
* Report UTC time, not local time, in audit logs. Standardize on ISO 8601 format

Allow performing boot & start operations in groups
Hosts could end up out of sync with each other if prune commands are run
manually or when new hosts are added.
Before rolling back confirm that the required container is available on
all hosts and roles.
If we get an error we'll only hold the deploy lock if it occurs while
trying to switch the running containers.
We'll also move tagging the latest image from when the image is pulled
to just before the container switch. This ensures that earlier errors
don't leave the hosts with an updated latest tag while still running the
older version.

Rollbacks stopped working after https://github.com/mrsked/mrsk/pull/99.
We'll confirm that a container is available for the first role on the
primary host before attempting to rollback.
* `-e [REDACTED]` → `-e SOME_SECRET=[REDACTED]`
* Replaces `Utils.redact` with `Utils.sensitive` to clarify that we're
indicating redactability, not actually performing redaction.
* Redacts from YAML output, including `mrsk config` (fixes#96)
Add a deploy lock for commands that are unsafe to run concurrently.
The lock is taken by creating a `mrsk_lock` directory on the primary
host. Details of who took the lock are added to a details file in that
directory.
Additional CLI commands have been added to manual release and acquire
the lock and to check its status.
```
Commands:
mrsk lock acquire -m, --message=MESSAGE # Acquire the deploy lock
mrsk lock help [COMMAND] # Describe subcommands or one specific subcommand
mrsk lock release # Release the deploy lock
mrsk lock status # Report lock status
Options:
-v, [--verbose], [--no-verbose] # Detailed logging
-q, [--quiet], [--no-quiet] # Minimal logging
[--version=VERSION] # Run commands against a specific app version
-p, [--primary], [--no-primary] # Run commands only on primary host instead of all
-h, [--hosts=HOSTS] # Run commands on these hosts instead of all (separate by comma)
-r, [--roles=ROLES] # Run commands on these roles instead of all (separate by comma)
-c, [--config-file=CONFIG_FILE] # Path to config file
# Default: config/deploy.yml
-d, [--destination=DESTINATION] # Specify destination to be used for config file (staging -> deploy.staging.yml)
-B, [--skip-broadcast], [--no-skip-broadcast] # Skip audit broadcasts
```
If we add support for running multiple deployments on a single server
we'll need to extend the locking to lock per deployment.
Commander had version/destination solely to incrementally accumulate CLI
options. Simpler to configure in one shot.
Clarifies responsibility and lets us introduce things like
`abbreviated_version` in one spot - Configuration.
Less work for broadcast commands to take on.
Also fixes a bug where rollback on hosts without a running container
would stop the container they had just started.
If we don't supply a version when deploying we'll use the result of
docker image ls to decide which image to boot. But that doesn't
necessarily correspond to the one we have just built.
E.g. if you do something like:
```
mrsk deploy # deploys git sha AAAAAAAAAAAAAA
git commit --amend # update the commit message
mrsk deploy # deploys git sha BBBBBBBBBBBBBB
```
In this case running `docker image ls` will give you the same image
twice (because the contents are identical) with tags for both SHAs but
the image we have just built will not be returned first. Maybe the order
is random, but it always seems to come second as far as I have seen.
i.e you'll get something like:
```
REPOSITORY TAG IMAGE ID CREATED SIZE
foo/bar AAAAAAAAAAAAAA 6272349a9619 31 minutes ago 791MB
foo/bar BBBBBBBBBBBBBB 6272349a9619 31 minutes ago 791MB
```
Since we already know what version we want to deploy from the config,
let's just pass that through.
