Watchmaker

**Summary**:

* [[PR 280][280]] Modifies the dynamic import of boto3 to use only absolute
imports, as the previous approach (attempt absolute and relative import)
was deprecated in Python 3.3
* ntp-client-windows-formula:
* Stops using deprecated arguments on reg.present states, which cleans up
extraneous log messages in watchmaker runs under some configurations
* join-domain-formula:
* (Windows) Sets the DNS search suffix when joining the domain, including
a new pillar config option, `ec2config` to enable/disable the EC2Config
option that also modifies the DNS suffix list.

**Summary**:

* [[Issue 270][270]] Defaults to a platform-specific log directory when
call from the CLI:
* Windows: `${Env:SystemDrive}\Watchmaker\Logs`
* Linux: `/var/log/watchmaker`
* [[PR 271][271]] Modifies CLI arguments to use explicit log-levels rather
than a verbosity count. Arguments have been adjusted to better accommodate
the semantics of this approach:
* Uses `-l|--log-level` instead of `-v|--verbose`
* `-v` and `-V` are now both used for `--version`
* `-d` is now used for `--log-dir`

**Summary**:

* [[Issue 262][262]] Merges lists in pillar files, rather than overwriting
them
* [[Issue 261][261]] Manages the enabled/disabled state of the salt-minion
service, before and after the install
* splunkforwarder-formula
* (Windows) Ignores false bad exits from Splunk clone-prep-clear-config

**Summary**:

* [[PR 251][251]] Adds CloudFormation templates that integrate Watchmaker
with an EC2 instance or Autoscale Group
* join-domain-formula
* (Linux) Corrects tests that determine whether the instance is already
joined to the domain

[251]: https://github.com/plus3it/watchmaker/pull/251

**Summary**:

* ash-linux-formula
* Reduces spurious stderr output
* Removes notify script flagged by McAfee scans
* splunkforwarder-formula
* (Windows) Clears system name entries from local Splunk config files

**Summary**:

* [[Issue 238][238]] Captures all unhandled exceptions and logs them
* [[Issue 234][234]] Stops the salt service prior to managing salt formulas,
to ensure that the filesystem does not throw any errors about the files
being locked
* [[Issue 72][72]] Manages salt service so the service state after
watchmaker completes is the same as it was prior to running watchmaker. If
the service was running beforehand, it remains running afterwards. If the
service was stopped (or non-existent) beforehad, the service remains
stopped afterwards
* [[Issue 163][163]] Modifies the `user_formulas` config option to support
a map of `<formula_name>:<formula_url>`
* [[PR 235][235]] Extracts salt content to the same target `srv` location
for both Window and Linux. Previously, the salt content was extracted to
different points in the filesystem hierarchy, which required different
content for Windows and Linux. Now the same salt content archive can be
used for both
* [[PR 242][242]] Renames salt worker param `content_source` to
`salt_content`
* systemprep-formula
* Deprecated and removed. Replaced by new salt content structure that
uses native salt capabilities to map states to a system
* scc-formula
* Deprecated and removed. Replaced by scap-formula
* scap-formula
* New bundled salt formula. Provides SCAP scans using either `openscap`
or `scc`
* pshelp-formula
* New bundled salt formula. Installs updated PowerShell help content to
Windows systems
