Overview
The Controller service provides the API for orchestrating a collection of debugger agents to perform debugging tasks. These agents are each attached to a process of an application which may include one or more replicas.
The debugger agents register with the Controller to identify the application being debugged, the Debuggee. All agents that register with the same data, represent the same Debuggee, and are assigned the same +debuggee_id+.
The debugger agents call the Controller to retrieve the list of active Breakpoints. Agents with the same +debuggee_id+ get the same breakpoints list. An agent that can fulfill the breakpoint request updates the Controller with the breakpoint result. The controller selects the first result received and discards the rest of the results. Agents that poll again for active breakpoints will no longer have the completed breakpoint in the list and should remove that breakpoint from their attached process.
The Controller service does not provide a way to retrieve the results of a completed breakpoint. This functionality is available using the Debugger service.

Instance Method Details
#list_active_breakpoints(debuggee_id, wait_token: nil, success_on_timeout: nil, options: nil) {|result, operation| ... } ⇒ Google::Devtools::Clouddebugger::V2::ListActiveBreakpointsResponse
Returns the list of all active breakpoints for the debuggee.
The breakpoint specification (+location+, +condition+, and +expressions+ fields) is semantically immutable, although the field values may change. For example, an agent may update the location line number to reflect the actual line where the breakpoint was set, but this doesn't change the breakpoint semantics.
This means that an agent does not need to check if a breakpoint has changed when it encounters the same breakpoint on a successive call. Moreover, an agent should remember the breakpoints that are completed until the controller removes them from the active list to avoid setting those breakpoints again.

Registers the debuggee with the controller service.
All agents attached to the same application must call this method with exactly the same request content to get back the same stable +debuggee_id+. Agents should call this method again whenever +google.rpc.Code.NOT_FOUND+ is returned from any controller method.
This protocol allows the controller service to disable debuggees, recover from data loss, or change the +debuggee_id+ format. Agents must handle +debuggee_id+ value changing upon re-registration.
