[Discover] Group multifields in document table view

[majagrubic]

Similar to grouping multifields in sidebar, we need to group multifields in the table view. We've considered the following options:

1. Show a tooltip, similar to how it's done in the sidebar
   Pros: looks nice, not too complicated to implement
   Con: the field becomes "hidden", which, in a document view, I'm not sure we want. As a user, I'd expect to be able to see all the fields at a glance

2. Group multifields in the table itself, so that somehow there's a visible distinction between them
   Pros: fields visible at a glance, not too complicated to implement
   Con: inconsistent?
   Here's what I was thinking of:

3. Hybrid between option 2 and 3: just show the tooltip behind the field name showing other (multifield) names, and only list the values where value is different than the parent value.
   Pros: looks nice, fields visible at a glance
   Cons: inconsistent, complex to implement

Note that the ES is planning for keyword multifield to go away by 8.0.0. If it goes according to plan, we ideally don't want to spend too much time/effort implementing this now. The ideal solution is something that looks nice, doesn't require too much effort to implement, and can easily be removed once the time comes 😬

Any thoughts on this? @andreadelrio

@majagrubic I think option 2 works. For consistency, I'd add a title like in the screenshot above.
Questions:

• Do we want to add the type of field token to the left of the field name? (i.e. t for string, etc)
• Will the multifields also have the four actions available? (i.e. filter for value, filter out value, filter for field present, toggle column)

I think having field type next to the field name is optional; I don't think a lot of information is lost without it. We should add actions, yes, since the sidebar already has actions on those fields.

@majagrubic Here's a mock showing actions for mutifields.
