add s3 circuit breaker support for 'simultaneous request count' and 'simultaneous request bytes' limitations

Browse Source 
configure s3 circuit breaker by 'command_s3_circuitbreaker.go':
usage eg:
# Configure the number of simultaneous global (current s3api node) requests
s3.circuit.breaker -global -type count -actions Write -values 1000 -apply

# Configure the number of simultaneous requests for bucket x read and write
s3.circuit.breaker -buckets -type count -actions Read,Write -values 1000 -apply

# Configure the total bytes of simultaneous requests for bucket write
s3.circuit.breaker -buckets -type bytes -actions Write -values 100MiB -apply

# Disable circuit breaker config of bucket 'x'
s3.circuit.breaker -buckets x -enable false -apply

# Delete circuit breaker config of bucket 'x'
