task/TTS-3 - Initial service generation with renamed schema

[jchuahtacc]

Transforms and new generated services. Please review a list of changes to each open API spec here:

https://github.com/tapis-project/tapis-typescript/wiki/TAPIS-API-Transformations

General notes about transforms to achieve consistency:

• Any schema named "NewSomething" on an action that was called "create_something" was renamed to be "ReqCreateSomething", to match other services
• hello, ready and healthcheck endpoints were retagged as Health, to create one wrapper class for all similar functions

PGRest has an issue with a type for a property set as a oneOf array. The openapi-generator-cli does not handle these well, so the transform in this PR removes the explicit type. We should discuss potential impacts

TODO:

• Remove health checks
• Missing Meta and SK transforms in Wiki
• UpdateMultipleCollectionItemWhereSubValue any is unacceptable. Possibly requires a manual transform after generation
