Feature #6780: Implement type checking/coercion for action args 
https://projects.puppetlabs.com/issues/6780

The expectation is that actions should be able to transparently have 
typechecked signatures, and that automatic coercions will happen for certain 
argument types.

Consider:

    option "--foo FOO", String
    # => option requires a string; should it automatically to_s on an array?  I 
suspect not...

    option "--foo FOO", Puppet::Resource::Catalog
    # => option requires a catalog, and should automatically convert.
    # also, it should have "--foo-type TYPE", [:yaml, :pson, :string, :hash] 
added...

This makes interfacing the rich type system of Ruby with the command line's 
simple String-based interface simple.
