* 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.

* Commit the IConnection interface change, forgot in previous commit
* Fix the issue that onClosed request is cancelled by ActorCollection
* Enable the remote kv store knob
* Remove FlowProcess.actor.cpp and move functions to RemoteIKeyValueStore.actor.cpp; Add remote kv store delay to avoid race; Bind the child process to die with parent process
* Fix the bug where one process starts storage server more than once
* Add a please_reboot_remote_kv_store error to restart the storage server worker if remote kvs died abnormally
* Remove unreachable code path and add comments
* Clang format the code
* Fix a simple wait error
* Clang format after merging the main branch
* Testing mixed mode in simulation if remote_kvs knob is enabled, setting the default to false
* Disable remote kvs for PhysicalShardMove which is for RocksDB

1. Introduce processDiskReadSeconds and processDiskWriteSeconds, which stands for disk read/write times `since the last logging`. They can only be obtained on Linux and macOS, and will be 0 on Windows and FreeBSD;
2. Rename `busyTicks` to `IOMilliSecs`;
3. On FreeBSD, the metrics should be collected among all devices.
1. Add a trace event when a database is created and move the cluster file / connection string from ClientStart to the new trace event
2. Add a detail for the path to the image being loaded
3. Add a detail for whether a client library is primary or not
4. Set a thread name for each external client thread that includes the release version
When compiling FDB using clang++, self-assign warning appears due to the
code
pos = littleEndian32(pos);
in Atomic.h, which expands to
pos = pos;
as littleEndian32 is defined as
#define littleEndian32(value) value
This warning is not interesting, but annoying, by adding a
no-side-effect casting, the warning is suppressed.
This merges release-6.3 branch right before it was fully formatted.
There were quite a few conflicts that are resolved here. CoroFlow had
a check for OOM errors introduced in 6.3, but didn't seem applicable in
the new implmentation which seems to use boost.
