* REST KmsConnector implementation
Description
diff-1: Address review comments.
Add utility interface to Platform namespace to
create and operate on tmpfile
diff-2: Address review comments
Link Boost::filesystem to CMake build process
Major changes includes:
1. Implement REST based KmsConnector implementation.
2. Salient features of the connector:
2.1. Two required configuration are:
a. Discovery KMS URLs - enable KMS discovery on bootstrap
b. Endpoint path configuration to construct URI to fetch/refresh
encryption keys
c. Configuration to provide "validationTokens" to connect with
external KMS. Patch implements file-based token validation scheme.
2.2. On startup, RESTKmsConnector discovers KMS Urls and caches
them in-memory. Extracts "validationTokens" based on input config.
2.3. Expose endpoints to allow fetch/refresh of encryption keys.
2.4. Defines JSON format to interact with external KMS - request &
response payload format.
3. Extend Platform namespace with an interface to create and operate on
tmp files.
4. Update Platform 'readFileBytes' and 'writeFileBytes' to leverage
fstream supported implementation.
NOTE: KMS URLs fetched after initial discovery will be persisted using
DynamicKnobs. It is TODO at the moment and shall be completed
once DynamicKnobs is feature complete
Testing
Unit test to validation following:
1. Parsing on "validation tokens" logic.
2. Construction and parsing of REST JSON request and response strings.
* EncryptKeyProxy server APIs for simulation runs.
Description
diff-2: FlowSingleton util class
Bug fixes
diff-1: Expected errors returned to the caller
Major changes proposed are:
1. EncryptKeyProxy server APIs:
1.1. Lookup Cipher details via BaseCipherId
1.2. Lookup latest Cipher details via encryption domainId.
2. EncyrptKeyProxy implements caches indexed by: baseCipherId &
encyrptDomainId
3. Periodic task to refresh domainId indexed cache to support
'limiting cipher lifetime' abilities if supported by
external KMS solutions.
Testing
EncyrptKeyProxyTest workload to validate the newly added code.

In this patch, for a given test, it is possible to override the knob
values, e.g.
[[test]]
[[test.knobs]]
watch_timeout = 999
will set the client knob WATCH_TIMEOUT to 999 during the test. The
original value will be recovered after the test is over.
Description
Major changes proposed are:
1. Rename ServerKnob->ENABLE_ENCRYPT_KEY_PROXY to
ServerKnob->ENABLE_ENCRYPTION. Approach simplifies enabling
controlling encyrption code change using a single knob (desirable)
2. Implement EncyrptKeyVaultProxy simulated interface to assist
validating encyrption workflows in simulation runs. The interface
is leveraged to satisfy "encryption keys" lookup which otherwise
gets satisfied by integrating organization preferred Encryption
Key Management solution.
Testing
Unit test to validate the newly added code
add Finduring, and include into fdbserver
add BOOST asio/uring settings to fdbserver compile
move portable rocks, liburing up to be configurable at build time.
