Currently, a std::string is copied unnecessarily for every key and value
in a trace event.
This actually showed up in a jemalloc heap profile while I was
investigating something unrelated. I was surprised to see it since these
allocations should have a very short lifetime.
Description
Major changes include:
1. GetEncryptByKeyIds cache elements can expire.
2. Update iterator after erasing an element during refresh encryption keys
operation.

* Work around flow trace's data race bug
BaseTraceEvent::setNetworkThread() and flushTraceFile[()|Void()]
has a long-standing race condition for traceEventThrottlerCache global
when flushTraceFileVoid() is not called from the network thread.
This race dates back to 2017 (commit hash 80e5fecfe2),
so before the race itself is fixed, work around the problem.
* Remove call to flushTraceFileVoid() from MkCertCli
* Apply clang format
* Close trace file when error happens in runNetwork().
* Improve the bestCount algorithm in getLeader().
In the current implementation, if the nominees are [0,1], the chosen leader will be 1, which is an exception to other cases and our expectation that if 2 nominees have the same frequency, the one with lower id will be the leader.
* Remove unnecessary new statement.
stream will never be a nullptr.
* Move self->dnsCache out of lambda capture.
Member variables are not capture by default, thus, `host` and `service` are not captured. This somehow successfully compile, but throws std::bad_alloc or basic_string::_S_create exceptions when we call `host+":"+service` in dnsCache.remove().
* Revert unintended change.
* Address comments.
* fixup! Fix the XmlTraceLogFormatter
The original escape process uses a `loop` while the code is actually not
an ACTOR. So the actorcompiler is not reacting. This causes the escape
not escaping the XML fields properly.
* fixup! Reformat source
* KmsConnector implementation to support KMS driven CipherKey TTL
Description
KMS CipherKeys can be of two types:
1. Revocable CipherKeys: having a finite lifetime, after which the CipherKey
shouldn't be used by the FDB.
2. Non-revocable CipherKeys: ciphers are not revocable, however, FDB would
still want to refresh ciphers to support KMS cipher rotation feature.
Patch proposes following change to incorporate support for above defined cipher-key
types:
1. Extend KmsConnector response to include optional 'refreshAfter' & 'expireAfter'
time intervals. EncryptKeyProxy (EKP) cache would define corresponding absolute refresh &
expiry timestamp for a given cipherKey. On an event of transient KMS connectivity outage,
a caller of EKP API for a non-revocable key should continue using cached cipherKey until
it expires.
2. Simplify KmsConnector API arena handling by using VectorRef to represent component
structs and manage associated memory allocation/lifetime.

* Add TRACING_SPAN_ATTRIBUTES_ENABLED Knob, default false.
In order to prevent accidental leakage of PII to external tracing collector services,
we've added a knob to prevent additional attributes to be added to spans unless explicitly
enabled by the user.
* Enable span attributes knob for unit tests.
Adding GetEncryptCipherKeys and GetLatestCipherKeys helper actors, which encapsulate cipher key fetch logic: getting cipher keys from local BlobCipherKeyCache, and on cache miss fetch from EKP (encrypt key proxy). These helper actors also handles the case if EKP get shutdown in the middle, they listen on ServerDBInfo to wait for new EKP start and send new request there instead.
The PR also have other misc changes:
* EKP is by default started in simulation regardless of. ENABLE_ENCRYPTION knob, so that in restart tests, if ENABLE_ENCRYPTION is switch from on to off after restart, encrypted data will still be able to be read.
* API tweaks for BlobCipher
* Adding a ENABLE_TLOG_ENCRYPTION knob which will be used in later PRs. The knob should normally be consistent with ENABLE_ENCRYPTION knob, but could be used to disable TLog encryption alone.
This PR is split out from #6942.
