Release 1.7.0

Features

• Added the trace_methods_duration_threshold config option. When using the trace_methods config option with wild cards, this
  enables considerable reduction of overhead by limiting the number of spans captured and reported (see more details in config
  documentation).
  NOTE: Using wildcards is still not the recommended approach for the trace_methods feature
• Add Transaction#addCustomContext(String key, String|Number|boolean value) to public API
• Added support for AsyncHttpClient 2.x
• Added global_labels configuration option.
  This requires APM Server 7.2+.
• Added basic support for JMS- distributed tracing for basic scenarios of send, receive, receiveNoWait and
  onMessage. Both Queues and Topics are supported. Async send APIs are not supported in this version.
  NOTE: This feature is currently marked as "Incubating" and is disabled by default. In order to enable, it is
  required to set the disable_instrumentations
  configuration property to an empty string.
• Improved OSGi support: added a configuration option for bootdelegation packages (#641)
• Better span names for SQL spans. For example, SELECT FROM user instead of just SELECT (#633)
