docs: A call-back method called when the feature is to be enabled in a given
  runtime configuration scope.
  <p>
  The responsibility of the feature is to properly update the supplied runtime configuration context
  and return {@code true} if the feature was successfully enabled or {@code false} otherwise.
  <p>
  Note that under some circumstances the feature may decide not to enable itself, which
  is indicated by returning {@code false}. In such case the configuration context does
  not add the feature to the collection of enabled features and a subsequent call to
  {@link javax.ws.rs.core.Configuration#isEnabled(javax.ws.rs.core.Feature)} or
  {@link javax.ws.rs.core.Configuration#isEnabled(Class)} method
  would return {@code false}.
  <p>
  
  @param context configurable context in which the feature should be enabled.
  @return {@code true} if the feature was successfully enabled, {@code false}
  otherwise.
