AutoIndent update implementation

[jpogran]

In VSCode version 1.9 auto-indent was updated. Functionality is documented here.

This requires usto update the https://github.com/lingua-pupuli/puppet-vscode/blob/master/languages/puppet.configuration.json file, with a new indentationRules block that contains regex patterns for increasing and decreasing the indent. According to the documentation, we should also change the name from puppet.configuration.json to puppet-languages-configuration.json in order to get validation and editor support.

I did a POC locally and have it working somewhat, but it's controlled by a regex so it's going to need some further work to catch all the different cases we have. Examples show a known list of keywords ( if, else, when, do, etc) so we have a possible problem in that we want indentation to occur after both puppet language keywords (the puppet dsl) as well as any type name (file, package, etc)

This was reported by Joseph Citarello.

The regex can account for the Puppet DSL keywords but when it comes to the type declarations it is much harder.

For example:

file { 'foo':

This isn't caught by the existing configuration because of the string followed by the colon. Adding a single quote and colon begins to break the regex.

I think for the 0.11 release we can correct the file name and add indentation support for the keywords in the DSL. Auto indentation for the types will need to come in a subsequent PR
