By default, statsd metrics can be sent by the swift account, container and object storage services for diagnostic and monitoring purposes, but are disabled by default. This change exposes charm config settings that allow it to be enabled by setting 'statsd_host' to a non-empty value. 'statsd_port' and 'statsd_sample_rate' are also supported for changing the destination port and rate at which metrics are collected. Closes-Bug: #1729770 Change-Id: If1bf3ced8a9ed07af81f352eb0263659d147e3aa
