Operations Center Context Plugin 2.176.0.6

Problem: Configuration Snippets from Operations Center could be applied before Jenkins was fully loaded leading to loss of configuration

Fix: Configuration Snippets are no longer applied until we are sure that the Jenkins configuration has been deserialized

Problem: When a controller is disconnected from Operations Center some but not all Configuration Snippets would be removed

Fix: Configuration Snippets are no longer removed when a controller is removed from an Operations Center cluster so that the existing configuration can be tweaked or removed as desired.
