Support cancel in ADLS Gen2 blob delete job

[JasonYeMSFT]

Which version of the AzCopy was used?

10.17.0

Which platform are you using? (ex: Windows, Mac, Linux)

Windows, Mac, Linux

What command did you run?

./azcopy remove "https://mystorageaccount.dfs.core.windows.net/bc0/FORM.mpeg" --from-to=BlobFSTrash --recursive --log-level=DEBUG;

I removed my account key environment variables.

What problem was encountered?

The job doesn't provide a cancel mechanism like non-HNS blob delete jobs where you can enter "cancel" in stdin to cancel the job.

Have you found a mitigation/solution?

Kill the process will effectively cancel the job but AzCopy won't be able summarize the job and gracefully exit.
