add the ability to resolve deprecated modules

[binford2k]

When modules are deprecated, there's often a replacement suggestion. This tool should resolve those to help end users keep up with changes.

Ideally, it would resolve the existing dependencies and write those out to the file, but also add a commented out mod declaration for the replacement. This would ensure that the resolved Puppetfile continued to work properly, even if you took no action.

An example might look like

####### resolved dependencies #######
mod 'nwops-format', '0.1.0'    # deprecated  
# mod 'puppet-format', '0.1.0' # suggested alternative

mod 'puppetlabs-stdlib', '8.5.0'
mod 'puppetlabs-apt', '8.5.0'
mod 'puppetlabs-inifile', '5.4.0'
mod 'puppet-zypprepo', '4.0.1'
mod 'puppet-archive', '6.1.0'
mod 'puppetlabs-concat', '7.3.0'
