trace: Allow field names to be separated by .s (#1027) ...

## Motivation

In order to support conventions that add namespacing to `tokio-trace`
field names, it's necessary to accept at least one type of separator
character. Currently, the `tokio-trace` macros only accept valid Rust
identifiers, so there is no clear separator character for namespaced
conventions. See also #1018.

## Solution

This branch changes the single `ident` fragment matcher for field names
to match *one or more* `ident` fragments separated by `.` characters.

## Notes

The resulting key is still exposed to `tokio-trace-core` as a string
constant created by stringifying the dotted expression. However, if
`tokio-trace-core` were later to adopt a first class notion of
hierarchical field keys, we would be able to track that change in
`tokio-trace` as an implementation detail.

Closes #1018.
Closes #1022.
