* [Ada] Operation security scopes are ignored when generating the server (#1043)
- Update fromOperation() to keep the operation required scopes for each auth
method and store that information in the x-scopes vendor extensions attribute
- Update postProcessOperationsWithModels() to process the operation required
scopes and build a list of authMethods which only contain the required scopes
for the operation and store these authMethods in the x-auth-scopes attribute.
- Update postProcessAuthMethod() to handle the logic of filtering and building
the operation authMethod (new instances are created because we must not
modify the global authMethod definitions)
- Update the Ada server templates to use the x-auth-scopes instead of authMethods
Add a URL prefix parameter for the Ada server instantiation
* Fix Ada code generator
- update to generate Ada style type names (broken by the use of Camelize)
- update the templates for Ada Util and Swagger libraries
* Update generated GNAT project to add the 'utilada_xml' dependency
* Update the Ada samples
* Fix compilation of the petstore Ada sample
