Example notebook demonstrating use of tags for organizing and retrieving resources and cost breakdown

**Is your feature request related to a problem? Please describe.**
Customers want to organize Braket resources they create. For instance, they might want to group quantum tasks that belong to the same experiment and later retrieve them.

**Describe the solution you'd like**
An example notebook which should demonstrate:
* Using tags to tag Braket resources (AwsQuantumTask, AwsQuantumTaskBatch, AwsQuantumJob)
* Retrieving these tagged resources using the tag names/values (See [this](https://github.com/amazon-braket/amazon-braket-sdk-python/issues/630) for reference)
* Using tags to view detailed breakdown for the costs (See [this](https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/cost-alloc-tags.html) for details)

**Describe alternatives you've considered**
We could put this in the Developer guide
