Fix 7955: allow datetime filtering on /spend/logs

[rewbs]

Allow datetime filtering on /spend/logs

This change allows you to query the spend logs with a datetime range filter. This functionality is currently unavailable (the existing start_date and end_date parameters do something altogether different).

Relevant issues

Implements #7955 7955

Type

🆕 New Feature

Changes

• Add additional params to /spend/logs
• Improve documentation of /spend/logs
• Pass new params down the chain of query functions, without changing their overall structure (though I am not sure why we go from the spendlog API implementation into a generalised query function which then branches on the table type anyway? seems like an unnecessary level of indirection).

[REQUIRED] Testing - Attach a screenshot of any new tests passing locally

I have not included tests yet, happy to add them if this PR is considered desirable.

Hi @rewbs this is great. Can you share a screenshot of this working for you as expected?

[krrishdholakia]

do we need this dependency?

[rewbs]

IMO yes, because I don't think it's worth re-implementing flexible datetime parsing. It is a mature and maintained library.

Sure, here are a couple of curl requests. In the first you can see a start_time feature just a date, as well as an api_key filter. There are 2 matching requests for that key after the start_time. In the second request, we add an end_time parameter with a full datetime stamp that excludes the later request.
