Acceleration documentation: intrinsic values are completely ignored

[kris-watts-gravwell]

Enhancement

What is the enhancement to be made?

Add blurb about acceleration and intrinsic values/fields. We don't mention them at all.

We should also point at the intrinsic module AND a link to an example ingester/preprocessor that adds EVs.

Why should we make this change? (Business justification? What problem is the feature trying to solve?)

Couple users completely glossed over intrinsic values as being a thing because we don't reference them enough.

Any other comments?

cross reference the acceleration section and example ingester/preprocessor here too: https://docs.gravwell.io/search/search.html#intrinsic-enumerated-values
