[FR] Explicitly provide task name when enqueuing new Cloud Task

[wnielson]

Is your feature request related to a problem? Please describe.
No.

Describe the solution you'd like
The Cloud Tasks API allows you to specify a task's name explicitly but the SDK does not currently expose this. This is useful for task de-duplication, for example. It would be great to expose this via TaskOptions through a name property like so:

const queue = getFunctions().taskQueue("taskFunction");
queue.enqueue(
  { ... },
  { name: "task-name" }
);

Describe alternatives you've considered
The workaround is to use the @google-cloud/tasks SDK directly like so:

import { CloudTasksClient } from "@google-cloud/tasks";

const client = new CloudTasksClient();

const name = "task-name";
const projectId = "project-name";
const location = "us-central1";
const functionName = "taskFunction";
const serviceAccountEmail = `${projectId}@appspot.gserviceaccount.com`;

const parent = client.queuePath(
  projectId,
  location,
  functionName
);

const url = `https://${location}-${projectId}.cloudfunctions.net/${functionName}`;

client
  .createTask({
    parent: parent,
    task: {
      name: `${parent}/tasks/${name}`,
      httpRequest: {
        headers: {
          "Content-Type": "application/json",
        },
        body: Buffer.from(
          JSON.stringify({ data: {} })
        ).toString("base64"),
        httpMethod: "POST",
        url: url,
        oidcToken: { serviceAccountEmail },
      },
    },
  });

Additional context
While the solution above works, it is clearly far more verbose and cumbersome than if the firebase admin were to expose this functionality directly.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

I think this has been implemented in #2216?
