Document keywords and whether or not they're reserved

[mxwli]

As of 3626, we've decided that the keyword list should be documented, as well as whether or not each keyword is reserved. Additionally, we should document whether or not the status of the keyword complies with whether or not it's reserved in Postgres. In the following table, NA means the keyword doesn't exist in PG.

@andyfengHKU this would go in the Cypher manual, correct? Trying to think of which page exactly it would fit best.

I think so. You can make the final call here.
