Delete one or more buckets. Buckets must be empty before you can delete them.
Be certain you want to delete a bucket before you do so, as once it is
deleted the name becomes available and another user may create a bucket with
that name. (But see also "DOMAIN NAMED BUCKETS" under "gsutil help naming"
for help carving out parts of the bucket name space.)
Continues silently (without printing error messages) despite
errors when removing buckets. If some buckets couldn't be removed,
gsutil's exit status will be non-zero even if this flag is set.
If no buckets could be removed, the command raises a
"no matches" error.
