Fixes an issue where the crosDomain flag was being incorrectly reported to users via error objects and response objects as defaulting to true, when it was in fact defaulting to false.

Deprecates the crossDomain flag in favor of allowing the configuration of the request and the browser to dictate whether or not a preflight request is necessary. Adds deprecation messages with advice about how to force CORS preflights. Ultimately, the boolean flag does not make sense, as there are a lot of factors that dictate CORS preflight use and they may vary by browser/environment.

Resolves #6663

Fixes an issue where the `crosDomain` flag was being incorrectly reported to users via error objects and response objects as defaulting to `true`, when it was in fact defaulting to `false`.

Deprecates the `crossDomain` flag in favor of allowing the configuration of the request and the browser to dictate whether or not a preflight request is necessary. Adds deprecation messages with advice about how to force CORS preflights. Ultimately, the boolean flag does not make sense, as there are a lot of factors that dictate CORS preflight use and they may vary by browser/environment.
