Bug #7867: node names should work consistently across all supported
configurations and platforms

# Overview #
Currently different values for a node's name are not consistently allowed or
disallowed by Puppet. For example, a node name of foo::bar will work when
using an ENC on a POSIX filesystem, but will not work if the user is running
Puppet on an NTFS filesystem. Furthermore, this node name won't work if node
definitions are being used, e.g:
<pre>
node foo::bar {
# syntax error
}
</pre>
# Expected Behavior #
In order to support effective communication and documentation for the end user
node names should be consistently valid regardless of the configuration or
platform Puppet is running on. As an user, I expect that I can switch from an
ENC to node definitions or from ext3 to NTFS and my system will still function.
# Actual Behavior #
Node names that are valid in some configurations will throw cryptic and
difficult to diagnose errors. For example, node foo::bar { } will throw a
parse error when used with node definitions and will throw a "could not write
file" (or similar) error when used with NTFS.
# Suggested Fix #
The following implementation is only a suggestion. Any implementation that can
be consistently used across all supported configurations of Puppet would be
considered a valid fix to this bug.
Please keep in mind the node_name value is used as a primary key when
interfacing with third party systems. In this way, the solution should also
avoid limiting the number of third party systems Puppet can communicate with.
For example, a node name that is supported and could not be URL encoded would
make it difficult to interface with a REST API.
The current suggestion is to support some hybrid of POSIX "Fully portable
filenames" and RFC 1034 section 3.5 hostnames as valid node names
