FlowTransport: Don't immediately mark connections failed
...
In connectionKeeper(), when a connection is failed for
FAILURE_DETECTION_DELAY, then only mark connection as failed.
This is much closer to the original centralized behaviour, and also
adds more confidence on whether the connection is actually failed.

ConsistencyCheck:Fix failue due to address inconsistency between process and worker
...
With TLS, a worker (or process) can have a TLS address and non-TLS address.
When a process is created in simulation, the primary address is TLS by default.
The non-TLS one is the TLS address port plus one.
In a connection between two workers, if their primary addresses do not enable
or disable TLS together, one worker will swap its primary address and secondary address
so that the TLS config of the two endpoints can match.
The swap can make the primary address no longer the TLS one that was created
when the process is created. And the swap only happens for worker instead of
process struct in simulation.
This swap can cause worker->address != process->address.
In checkForExtraDataStores actor, we use worker->address to check if a process
is killable and use the process->address to kill the process. The inconsistency
can cause simulation to kill a protected process that is not killable and leads
to simulation failure.

Refactor TLSParams into TLSConfig + LoadedTLSConfig
...
The idea being that we keep around a TLSConfig that the configuration
that the user has provided, and then when we want to intialize an SSL
context, we ask the TLSConfig to load all certificates and return us a
LoadedTLSConfig that is a concrete set of certificate bytes in memory.
initTLS now just takes the in-memory bytes and applies them to the ssl
context.
This is a large refactor to lead up into certificate refeshing, where we
will periodically check for changes to the certificates, and then
re-load them and apply them to a new SSL context.

FastRestore:Add debug to see why restore role is not connected
...
Reason: restore is a fdbserver who does not register with CC.
The new failure monitor changes how connection works for client and server.
For client, it does not connect to CC to get connected.
For server, it has to connect to CC to get connected.
Restore worker becomes the special role that behaves like a client but is a server.

FastRestore:Add FastRestoreClass and blob option
...
To simplify test in circus framework, we need a fastrestore class;
To get data from blob in real mode, restore worker should set up
blob credentials in order to call BackupContainer interface to
get all backup files.

Move crc32c from fdbrpc to flow
...
So that we can use it from a piece of flow code without breaking module
boundaries.
Also rename generated-constants to crc32c-generated-constants so that
it's more apparent that they're related files.

Establishing TLS connection through the handshake process is expensive and the fdbserver process can get easily saturated with doing repeated TLS handshakes with only a few hundreds of clients have bad certificate. Hence throttle the number of handshakes done on the server per client ip if it has a bad certificate.

Active Failure Monitoring no longer needed at server processes
...
This patch removes active failure monitoring at server processes.
Hence like client processes, servers no longer require continuously
publishing their membership to cluster controller.
When a process is marked as failed, we still need to know if it back
up at certain point, particularly when the reference count is
incremented. In that case, loadBalance may see AllAlternativesFailed
as failed. To overcome this problem, whenever peer references is
incremented and and the address is marked as failed, connectionKeeper
will bypass waiting for data and connects immediately to check if the
process is back up.
