--no-wait

**Related command**
az resource tag (there are many more)

**Is your feature request related to a problem? Please describe.**
`az resource tag` does not have a `--no-wait` flag. I need to tag a large number of resources and am not concerned with the response of each tag operation. Running the command in the background (`az resource tag ... &`) is not really a great option because of memory exhaustion due to all the python invocations.

What is the process for adding `--no-wait` to an existing command? Can we ensure that all (well, most, since it would not make sense for some) newly added commands have `--no-wait` by default?

**Describe the solution you'd like**
Most commands should support `--no-wait`.
