Missing metadata in output of `cargo metadata`

[ysimonson]

The output of cargo metadata does not include the following metadata fields:

• authors
• repository
• readme
• keywords
• categories

Is this a bug?

Context: These fields are among the list in C-METADATA of the API guidelines. There is an open ticket in clippy to check that these fields are defined. While a lint like this would typically lean on cargo_metadata, it's not presently possible to use it, as cargo_metadata uses the output of cargo metadata.

It seems fine by me to add all these! The relevant bit of code is here:

cargo/src/cargo/core/package.rs

Line 32 in de23b54

struct SerializedPackage<'a> {

OK, I can tackle this
