Find a way to pass information from the manifest to the `get` method.

Example for how this is currently used/implemented:

https://github.com/puppetlabs/puppetlabs-sqlserver/blob/b36eecf3fdadb3d45c9691fcac2e92c66fa3ad30/lib/puppet/provider/sqlserver_tsql/mssql.rb#L16-L26

  def get_config(instance = resource[:instance])
    config_resc = resource.catalog.resources.find do |resc|
      resc.title =~ %r{Sqlserver::Config} &&
        resc.original_parameters[:instance_name] =~ %r{#{instance}}i
    end
    if config_resc.nil?
      raise("Sqlserver_tsql[#{resource.title}] was unable to retrieve the config, please ensure the catalog contains sqlserver::config{'#{resource[:instance]}':}")
    end


    config_resc.original_parameters
  end

Puppet::Type's resource.catalog.resources provides access to other resources in the current catalog.

Possible implementation:

• Add a raw_catalog_access feature flag to https://github.com/puppetlabs/puppet-resource_api/blob/bd93dbac616baa4ffa18c99a0b45946c9d474fec/lib/puppet/resource_api/type_definition.rb#L37
• add catalog accessor to https://github.com/puppetlabs/puppet-resource_api/blob/bd93dbac616baa4ffa18c99a0b45946c9d474fec/lib/puppet/resource_api/base_context.rb#L13
• pass reference to resource.catalog to context every time one is created iff the raw_catalog_access feature is declared on the type definition
  • https://github.com/puppetlabs/puppet-resource_api/blob/bd93dbac616baa4ffa18c99a0b45946c9d474fec/lib/puppet/resource_api.rb#L428-L434 - might need additional changes if resource.catalog is not available at the class level
  • add pass through here: https://github.com/puppetlabs/puppet-resource_api/blob/bd93dbac616baa4ffa18c99a0b45946c9d474fec/lib/puppet/resource_api/io_context.rb#L8
• adjust testing for these changes
• update docs

Start with the proposed changes in lib/puppet/resource_api/type_definition.rb, base_context.rb, resource_api.rb, and io_context.rb. Trace how contexts are created and determine how catalog access should be passed when raw_catalog_access is declared. Update tests and documentation, and verify that get can access the current catalog without changing types that do not declare the feature.
