Feature request: Allow for specifying max version of inspec to be install

[sarahbakal]

Cookbook version

6.0.1

Chef-client version

12 through 13

Platform Details

Redhat, Solaris, AIX, Windows

Scenario:

Need to be able to specify that Inspec 2.x should not be installed but the highest version of 1.x is ok, while still allow our nodes in air-gapped environments to run the existing version of 1.x that they are on without the audit cookbook uninstalling and failing to reinstall the inspec gem with the version that was specified with node['audit']['inspec_version']

Something like allowing node['audit']['inspec_version'] = '<=1.51.21' or an attribute to prevent upgrades
