Support dotted notation path in all clauses

[amorton]

Document paths are now defined in the specification here Document Paths which builds on the def for a field name and array index in the same doc.

Spec was finished in #123

This ticket is to confirm they are supported in all places in the query clauses. Spec is not up to date for all clause syntax, but anywhere a command clause can reference a field in the document is probably a Dotted Notation Path

This will include:

• all paths in a filter clause
• projection to include or exclude a field
• paths in a sort clause (to be added)
• all paths for operators in the update clause.

@maheshrajamani and @tatu-at-datastax this is a catchall for the supported dotted notation, happy for you to close if it is not needed just following up from the spec change. I have updated the feature matrix, dotted paths are listed for the clauses, can you update if they are all done in the server.

At this point dotted notation works for:

• Filter clauses
• Update operators (ones supported)

but not on

• Projection
• Sort

as these are not implemented yet.

Dotted notation works for all implemented update operations (which are all operations planned to be supported).
