Maint: Be more clear that puppet queue is deprecated

- Remove link to old wiki docs
- Link to PuppetDB docs
- Say "deprecated" again
Maint: Move pkgdmg documentation into provider description; document changed behavior

This wiki page was more longwinded than it needed to be; you can really sum it
up in about four bullet points. So I did that, and removed the wiki link.

Also, while investigating what the wiki said, it became clear that this provider
no longer actually uses open-uri: a Kernel.open call was changed to File.open,
but apparently nobody was using file:/// URLs (or anything weirder), so it went
unnoticed. So I added some comments for future maintainers of this code.
Maint: Remove remaining links to wiki pages in Puppet source

These pages now all have better-maintained counterparts in the main docs site.
Maint: Update docs for schedule type and metaparameter

The wording of these was out of date and somewhat strange.
Maint: Improve/reduce documentation of relationship metaparemeters

These descriptions were too wordy and too inconsistent. I'm imposing a format on
them so they all look alike, and a casual reader can tell how many there are and
how their behaviors differ. I'm also adding links to the more detailed
documentation.
Maint: Standardize docs for refresh behavior in resource types; clarify exec docs

Service/mount/exec already documented that they do the refresh thing, but it
wasn't organized in a predictable way. I'm imposing a convention of a bold
"Refresh" label, a reminder of where events come from, and a description of what
that type does when it gets one.

This commit also adds a lot more detail on how execs respond to refresh, since
it's actually really complicated and not the least bit intuitive. I also reworded
some of the older language near the top of the exec type, while I was in there.
Maint: Clarify docs for stage type and metaparameter

This was pretty disorganized and confusing. Now it's less so!
(#16570) Don't load the node object again in configurer

Avoid loading the node object again if we already have a catalog.
(PUP-1218) Add ssh-ed25519 support to the sshkey type
(PUP-1218) Teach the ssh_authorized_key provider about ssh-ed25519 too.
Bug 1051 (platforms mistook for versions)

Fix bug PUP-1051 by stripping out the extraneous platform info from the individual versions of the gems.
(maint) cron: Make the munge method for the command property more readable

The removal of leading and trailing spaces in cron commands was
performed using a perlism instead of just using String#strip.
Do that instead.
(PUP-1051) Add rspec test to verify fix
(main) Remove symlinks from acceptance harness

Git's cross platform handling of symlinks is problematic on windows, and
the symlinks are also causing problems in third party software like
Eclipse.  This commit removes them, and instead is explicit about which
pre-suite steps are executed, in what order, in the
config/{git,packages}/options.rb files.
(maint) Add a diagnostic check that lmhosts is running
(PUP-800) Add offset and length to Locatable base class in model

This adds offset and locatable as attributes in the pops model
and makes all objects in a Program model have this trait (except
the top level Program which is always from 0 to the entire length of
the source).

Further, the Program may now contain the line index, and may
contain the source text.
(maint) Remove stale commented code
(maint) Fix up type parser's handling of String

String parameterization not fully supported (in string form),
and previously non parameterized types were listed twice.
(PUP-716) Change Puppet::FileSystem::File to module methods

This changes the API in a new implementation in a file called file_.rb
The intent is that it should replace the implemntation in File,
or perhaps directly in a Puppet::FileSystem class.
(PUP-716) Change more tests after refactoring

This also fixes the spec_helper which had a reference to
FileSystem::File
