Request: logical operators for “where” filter

[Nikita Ourazbaev]

This would enable some powerful features which currently require doing a lot of looping or repetitive concat assignments.

For example:

assign articles_with_tag = blog.articles | where: 'tags' contains 'tag-1'

or

assign interactive_media = product.media | where: 'media_type', 'model' or 'video' or 'external_video'
