[Proposal] Add range argument to .valid_allin

[Dooor]

Summary

• Allow .valid_allin to receive Range as an argument like .valid_allin("2020/02/01".."2020/05/01").
• This change derives from the Changed valid_in to exclude valid_from = to and valid_to = from pull request.

Proposal

when Range with including end (e.g. "2020/02/01".."2020/05/01") is passed, it will be same as previous behavior

Code:  valid_allin(02/01..05/01) / valid_allin(from: 02/01, to: 05/01)
Query: from <= valid_from AND valid_to <= to

01/01         02/01         03/01         04/01         05/01         06/01
  |-------------|*************|*************|*************|-------------|
                ↑                                         ↑
               from(02/01)                                to(05/01)

when Range with excluding end (e.g. "2020/02/01"..."2020/05/01") is passed, it will raise error

Code:  valid_allin(02/01...05/01)

=> RuntimeError: Range with excluding end is not supported
