Update to stdlib 8 and puppet-archive 6

[Stan van Hoorn]

This module still depends on stdlib < 7.0.0 and puppet-archive < 6

Do you have any plans to update to versions stdlib 8 and puppet-archive 6?

Meanwhile, stdlib 9 deprecated functions like is_hash e.g. in https://bitbucket.org/landcareresearch/puppet-solr/src/72adc2ab8ad8e387bf5baf86d946f06f1b9490cc/manifests/init.pp#lines-289.

Hi, this bug hit me today, had to update stdlib for another module and is_hash() is no longer valid.

Probably want to be using is_a instead? https://forge.puppet.com/modules/puppetlabs/stdlib/reference#is_a
