Added metadata for April 2018 client library updates.

We need to generate POST/PATCH/DELETE for (I)EntityWithReferenceRequest.
A few of the base template methods did not have toggles for collection property initialization, so I added them where appropriate but set them to true by default, so it should not affect existing generated code.

Sanitize Parameter variables to fix errors

Updates IEntityRequestBuilder.Base.template.tt so that it does not create properties with the same name as the methods within the class (specifically request), by concatenating a "_" to the end of the property name.

* Added a test for validating custom PHP namespace property from the TypeWriter CLI. Fixed test metadata.
* Add support for specifying key-value properties from the Typewriter CLI.
* Fix broken tests.
* Updated test metadata to match preprocessing
* Changes support E2E testing when different target platforms are used in a test run for Typewriter. The TemplateProcessor host needs to be reset for the case when we target a new language. Otherwise the wrong *CodeWriter will be used and an unsupported cast will occur in the templates when trying to cast host.CodeWriter to the platform specific CodeWriter. The change to ConfigurationService.Settings is also required to reset the settings for configuring the TemplateWriter.
* Updated typewriter tests to be more descriptive
