Add global control plane code

[rohanshah18]

Problem

Global control plane support needs to be added to the Java SDK.

Solution

Add open api generated code for the global control plane.

1. Files under org.openapitools.client are auto generated and can be ignored during the review
2. Updated gradle build to gradle clean build for the github actions
3. Rearranged the test folders for adding collection tests
4. Updated build.gradle to add dependencies for the open api generated code

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update
• Infrastructure change (CI configs, etc)
• Non-code change (docs, etc)
• None of the above: (explain here)

Test Plan

Ran integration tests for the existing code base but future PR's will be adding unit and integration tests for each operations.

Overall code looks good to me, we'll need to integrate all of the generated control plane logic into PineconeIndexOperationClient to really test things out, but the passing builds should give us some confidence here.

It seems one of the integration test runs is failing. Specifically Java 17 with Gradle 7.3.1. Looks like the ConfigureIndexTest failed a bunch of different times on setUp(). The other failure is UpdateAndQueryTest where it looks like there was an assertion failure, which may be due to flakiness or freshness. Not sure if you want to try and address these before merging.

@austin-denoble That's correct! As we discussed internally, this PR is meant to add openAPI changes only and the future index operations tickets are meant to add integration tests for index operations.
Also you're currently working on the collections, those tickets will help us test the open api generated code for collections.
