FR: Add File.delete options property to count missing file as success

Is your feature request related to a problem? Please describe. I frequently find myself performing delete operations on files that may or may not exist. Similar to how Cloud Firestore’s delete operation works, I would like for the Cloud Storage delete operation to consider a non-existent file as a successful deletion. In other words, I want my delete operation to be considered successful if the file does not exist after the operation completes- regardless of if it did exist before the operation.

Describe the solution you’d like The delete operation (docs here) takes an optional options object, whose only parameter is currently userProject. I would like a new property to be available that I could use to enable this mechanism on a per-operation basis. The syntax might look something like:

await myBucket.file("thisFileMightNotExist.txt").delete({mustExist: false})

Describe alternatives you’ve considered The two alternatives are to either 1) run a File.exists operation first, or 2) handle deletion error in catch block. Both alternatives work, they’re just not very elegant. Alternative 1 technically also leaves an unlikely but possible scenario where the file is removed after the the exists operation but before the delete operation.

Additional context None.
