String constants for naming the various Trace components.

These strings will used when turning on tracing for the respective

components. The component list must be kept in sync with the

TraceComponentId enumeration.

The tracer uses the _traceComponentMask in form of a 64bit field to mask

the user configured components.

Please ensure that no more than 64 components are specified in the

TRACE_COMPONENT_LIST.

The following example shows the usage of trace component names.

The setTraceComponents method is used to turn on tracing for the

components: Config and Repository. The component names are passed as a

comma separated list.
