allow newer versions of yum-epel cookbook

[mburns]

Description

Allow newer versions (0.5.x - 3.x.y, inclusive) of the yum-epel cookbook, to support nodes using newer versions of Chef that don't support the most recent version supported by the cookbook.

yum-epel is on v3.1.0 and this cookbook shouldn't have any breaking changes by allowing newer versions as dependencies, given our simple use case.

Contribution Check List

• All tests pass.
• New functionality includes testing.
• New functionality has been documented in the README and metadata if applicable.

See CONTRIBUTING.md.

Thanks for your contribution! 😃

I'm not sure why you removed the ruby pessimistic operator. If you could, please, clarify the reason for that.

[zuazo]

Even if we update the version number, I think we should conserve the pessimistic operator, shouldn't we?

Hi @zuazo!

I've tweaked the logic to have an upper limit to the valid versions (up to and including the current ~> 3.1), so that we won't pull in a 4.x version in case they radically change behavior. Good suggestion.

Because of the simple use of yum-epel, all versions released (assuming your platform and cookbook dependency graph allows) appear to work for this cookbook's purposes.

Why? For complex run_lists or nodes moving to Chef 13+, it is nice to not be pinned to the old dependency version 0.5 from ~3.5 years ago. 0.7.

Hi, I would like to use this cookbook but I can't because of this little thing that was not fixed from about 1 year now.. There was removed only a char to allow upper versions to be got, its that hard to make that change and release a new version?

@zuazo let's merge or close this PR, please. Cheers!
