Add memo in pinot

[bowenxia]

What changed?
Add memo in pinot:
When write, add memo into search attribute
When read, get memo from search attribute and cleanup that field

NOTE: don't merge it until our customer test it locally

Why?
memo was stored in ES but can't be indexed(not in ES schema). We made the pinot schemas according to ES's schema, so we thought that we did't need memo in Pinot, but one customer was complaining about that.

How did you test it?
unit test
Also tested manually at local

Potential risks
not risk since Memo is not a functional attribute.
