Integrate cli as a binary built as part of tantivy-core

Pros

Builds every commit

Allows prospective users to try tantivy

Cons

Increases build time

Slows down core feature development

If every core feature requires changing the example cli, it will slow down review and fixing of core library functionality

Outline

Update to rust edition 2018

Add all datatypes supported by the library to the dialog

test locally with a dependency on master of local tantivy

Further work

Skip fields found in json, but not in the schema instead of erroring
