Enclave initialization was moved into its own goroutine to avoid blocking the main loop of the key manager worker. Once initialization is completed, the resulting state of the enclave is compared to the latest key manager status. If the latter has changed, initialization is performed again.
This will be useful when we deploy master secret rotation since new secrets may be generated while old secrets are being replicated which can result in an outdated state once initialization finishes.
