Keyword arguments for options

[asppsa]

Moneta's convention of using a hash as the last argument for most methods in order to pass in options has been deprecated in Ruby 2.7, and won't be supported at all in 3.0. As such, we should change the Moneta spec and the code to use keyword arguments for options instead.

so there are problems in the code as well in ruby3.0? I was thinking it was just a test suite issue

Yes, it's a problem across the package at present - you'll see a lot of options = {} at the end of function definitions. We'll need to go through and change these all to **options and then work out what breaks
