* Defer recoveredDiskFiles wait if Encryption data at-rest is enabled
Description
In the current code ClusterController startup wait for 'recoveredDiskFiles'
future to complete before triggered 'clusterControllerCore' actor, which
inturn starts 'EncryptKeyProxy' (EKP) actor resposible to fetch/refresh
encryption keys needed for ClusterRecovery as well interactions with
KMS.
Patch addresses a circular dependency where StorageServer initialization
depends on EKP, but, CC doesn't recruit EKP till 'recoveredDiskFiles' completes
which includes SS initialization. Given 'recoveredDiskFiles' is an optimization,
the patch proposes deferring the 'recoveredDiskFiles' future completion until
new Master recruitment is done as part of ClusterRecovery (unblock EKP singleton)
