Add telemetry hooks

[roshan]

This PR adds telemetry hooks to the Clerk Java SDK

Example messages

To create these, here's an example piece of code

Example hook exerciser

package org.example;

import com.clerk.backend_api.Clerk;
import com.clerk.backend_api.models.operations.GetUserListResponse;

public class Main {
    public static void main(String[] args) throws Exception {
        Clerk clerk = Clerk.builder()
                .bearerAuth("sk_test_your_key_here")
                .build();

        for (int i = 0; i < 10; i++) {
            GetUserListResponse resp = clerk.users().list().call();
            System.out.println(resp);
            System.out.println(resp.userList().map(x -> x.getFirst().emailAddresses()));
            Thread.sleep(1000);
        }
    }
}

As before, we're adding

• Three Speakeasy hooks:
  • Not SDKInit because that isn't yet supported for us because we can't get to the sk yet
• A random sampler that filters out 90% of events
• A deduplication sampler that ensures that a single process only fires one event per day
• Skipping via CLERK_TELEMETRY_DISABLED=1
• Debugging via CLERK_TELEMETRY_DEBUG=1
• A few unit tests for each of the bits.
• A pom.properties resource file to keep version information in an accessible place for later
  • If someone knows a less invasive way let me know
