fixes #5181

* application/json
* application/xml
* application/x-www-form-urlencoded

* Set requestBodyValue values to be an immutable Map, as "value". Previously stored as a normal String.
* This enables adding "errors" to the Map, for validation use

* note: getOAS3RequiredRequestBodyContentType requires state.spec,
* which is not available to state.oas3

swagger-client in versions =3.10.9 exports it's build artifacts in multiple ways.
One artifact is exposed as ES5 compatible code with ES6 imports.
We use this fact to utilize webpack tree shaking algorithm.
This commit also updates swagger-client to v3.10.0
and decreases bundle size for around 10%.

Import of helpers from swagger-client worked because of the fact
that commonjs exports are basically an objects that can be destructured.
Whenever swagger-client switches to ES6 imports as primary mechanism
of webpack consuptions imports like that will fail. This change makes
sure that import mechanism is both compatible with ES6 and commonjs
import systems.

Along with that rename default import of swagger-client
to more appropriate SwaggerClient.

As resolving applies to everything and not just specific builds
the resolve.aliases have been moved to one common place.

As versions of libraries that are both used by swagger-js and swagger-ui
may diverge in time, we must use webpack resolve aliases to make sure
that only one version of these libraries gets bundled.

Avoid mapping Immutable.Map as React children.
