This library is required for parsing multipart requests asynchronously
in Spring WebFlux. Framework treats this as an optional dependency, but
Boot auto-configures multipart support with Servlet by default.
Closes gh-10073
This commit adds a new json starter that gathers the core bits to read
and write json with dedicated Java 8 extensions.
The web-related starters have been improved to use the new starter
rather than relying on `jackson-databind` directly.
Closes gh-9297
