Exposing Stainless client library from the `AIProjectsBuilder`

[jpalvarezl]

Current state

More details here.

AIProjectClientBuilder builder = new AIProjectClientBuilder();

// Generated from TypeSpec definitions
ConnectionsClient connectionsClient = builder.buildConnectionsClient();
DatasetsClient datasetsClient = builder.buildDatasetsClient();
DeploymentsClient deploymentsClient = builder.buildDeploymentsClient();
EvaluationRulesClient evaluationRulesClient = builder.buildEvaluationRulesClient();
EvaluationsClient evaluationsClient = builder.buildEvaluationsClient();
EvaluationTaxonomiesClient evaluationTaxonomiesClient = builder.buildEvaluationTaxonomiesClient();
EvaluatorsClient evaluatorsClient = builder.buildEvaluatorsClient();
IndexesClient indexesClient = builder.buildIndexesClient();
InsightsClient insightsClient = builder.buildInsightsClient();
RedTeamsClient redTeamsClient = builder.buildRedTeamsClient();
SchedulesClient schedulesClient = builder.buildSchedulesClient();

// Client forwarding to Stainless OpenAI
EvalService evalService = evaluationsClient.getOpenAIClient();

What we want to do

• OpenAI client direct access
• Provide samples to update the Java code snippets for getting started and for how to switch to use the OpenAI client library directly
• TBD
