* [all] Adds strict spec option
Introduces an option to allow user customization of strict specification
behaviors. For instance, OpenAPI 3.x requires a path object name to be
prefixed with '/' so we append any missing '/', but this may not be
desirable to some users or generators. In this commit, this fix specifically is
the only modification affected.
* Clarify strict-spec docs, add option to README.md
* Update CLI options in docs/usage.md
* [cli] Support packageName as global option
CLI supports other package-related options (--api-package,
--model-package, --invoker-package). This aligns those options with
--package-name to avoid confusion about how to configure these options
where those are supported.
This intentionally does not apply a packageName getter/setter to
DefaultCodegen to reduce the footprint of this change.
* [gradle] Add packagName as global option
This makes packageName available as a global option, beside apiPackage,
modelPackage, and invokerPackage to reduce potential confusion about how
to configure the four of these options by generators which support them.
