* Introduce "default encryption domain"
Description
In current FDB native encryption data at-rest implementation,
an entity getting encrypted (mutation, KV and/or file) is categorized
into one of following encryption domains:
1. Tenant domain, where, Encryption domain == Tenant boundaries
2. FDB system keyspace - FDB metadata encryption domain
3. FDB Encryption Header domain - used to generate digest for
plaintext EncryptionHeader.
The scheme doesn't support encryption if an entity can't be categorized
into any of above mentioned encryption domains, for instance, non-tenant
mutations are NOT supported.
Patch extend the encryption support for mutations for which corresponding
Tenant information can't be obtained (Key length shorter than TenantPrefix)
and/or mutations do not belong to any valid Tenant
(FDB management cluster data) by mapping such mutations to a
"default encryption domain".
TODO
CommitProxy driven TLog encryption implementation requires every transaction
mutation to contain 1 KV, not crossing Tenant-boundaries. Only exception to
this rule is ClearRange mutations. For now ClearRange mutations are mapped
to 'default encryption domain', in subsequent patch appropriate handling
for ClearRange mutations shall be proposed.

Adding the following metrics:
* BlobCipherKeyCache hit/miss
* EKP: KMS requests latencies
* For each component that using encryption, they now need to pass a UsageType enum to the encryption helper methods (GetEncryptCipherKeys/GetLatestEncryptCipherKey/encrypt/decrypt) and those methods will help to log get cipher key latency samples and encryption/decryption cpu times accordingly.
