USAGE:

DESCRIPTION:
Remove a lifecycle configuration rule for the bucket by ID, optionally you can remove
all the lifecycle rules on a bucket with '--all --force' option.
EXAMPLES:
1. Remove the lifecycle management configuration rule given by ID "Documents" for testbucket on alias 'myminio'. ID is case sensitive.
{{.Prompt}} {{.HelpName}} --id "Documents" myminio/testbucket
2. Remove ALL the lifecycle management configuration rules for testbucket on alias 'myminio'.
Because the result is complete removal, the use of --force flag is enforced.
{{.Prompt}} {{.HelpName}} --all --force myminio/testbucket
