OpenAPI Schema Part Parsing

Parameters annotated with any of the following are parsed using the registered {@link oaj.oapi.OpenApiParser} and therefore support OpenAPI syntax and validation:

- {@link oaj.http.annotation.Header Header}
- {@link oaj.http.annotation.Query Query}
- {@link oaj.http.annotation.FormData FormData}
- {@link oaj.http.annotation.Path Path}
- {@link oaj.http.annotation.Body Body} (`Content-Type` must match "text/openapi")

For example, the following shows how a pipe-delimited list of comma-delimited numbers (e.g. "1,2,3|4,5,6|7,8,9") in a query parameter can be converted to a 2-dimensional array of `Longs`:

@RestMethod(method="GET", path="/testQuery") public void testQuery( @Query( name="queryParamName", collectionFormat="pipes", items=@SubItems( collectionFormat="csv", type="integer", format="int64", minimum="0", maximum="100" minLength=1, maxLength=10 ), minLength=1, maxLength=10 ) Long[][] queryParameter ) {...}

Input will be converted based on the types and formats defined in the schema definition.
Input validations such as `minLength/maxLength` that don't match the input will result in automatic `400 Bad Request` responses.

The following shows the same for a request body:

@RestMethod(method="POST", path="/testBody") public void testBody( @Body( parsers=OpenApiParser. class, defaultContentType="text/openapi", schema=@Schema( items=@Items( collectionFormat="pipes", items=@SubItems( collectionFormat="csv", type="integer", format="int64", minimum="0", maximum="100" minLength=1, maxLength=10 ) ), minLength=1, maxLength=10 ) ) Long[][] body ) {...}

The list of valid POJO types for parameters depends on type and format of the value or items/entries of the value.
For example, instead of `Longs` in the example above, we could also define a 2-dimensional array of POJOs convertible from `Longs`:

@RestMethod(method="POST", path="/2dLongArray") public void testBody(@Body(...) MyPojo[][] body) {...} // POJO convertible from a Long. public class MyPojo { public MyPojo(Long input) {...} }

Or even POJOs that take in arrays of `Longs[]`:

@RestMethod(method="POST", path="/2dLongArray") public void testBody(@Body(...) MyPojo[] body) {...} // POJO convertible from a Long[]. public class MyPojo { public MyPojo(Long[] input) {...} }

Or even POJOs that take in the whole 2-dimensional array:

@RestMethod(method="POST", path="/2dLongArray") public void testBody(@Body(...) MyPojo body) {...} // POJO convertible from a Long[][]. public class MyPojo { public MyPojo(Long[][] input) {...} }

As you can see, the complexity of possible input types expands significantly.
