Default to ISO 8601 date format in UI and add "June 26, 2016" as tooltip

[ypid]

Environment

• Python version: 3.7.3
• NetBox version: 2.10.1

Proposed Functionality

The current approach seems to be to use ISO 8601

SHORT_DATE_FORMAT = 'Y-m-d'          # 2016-06-26

where the logical order matters, for example in the changelog view that is sorted by time. For "free text" dates,

DATE_FORMAT = 'N j, Y'               # June 26, 2016

is used. I am proposing to use SHORT_DATE_FORMAT everywhere in the UI except in tooltips. And then augment dates as tooltip in DATE_FORMAT. This is because ISO 8601 is the standard for dates in written form. If the user ever needs to communicate a date via voice, they are expected to translate 2016-06-26 in their head or peek in the tooltip and say "June 26, 2016".

@jeremystretch commented on ISO 8601 in #1412 (comment) already so I assume there is some background to the current default. I still would like to discuss this.

Use Case

Consistency.

No.

Depending on the language for your region this may or may not be true. For latin based languages, it is more natural to say out loud(or in his head) 26th of June 2016(in the language of choice). Depends on the intent when using the tooltip. Anyway, idea is interesting for the tootip.

The date formats are all configurable.

I am looking into this now. Not sure how far I get. I will open a PR in the best case.
