This API function makes it possible to retrieve the X.509 certificate
used by clients to authenticate TLS connections.
(cherry picked from commit 0aec98dce2)
The tls-ca-cert or tls-ca-cert-dir configuration parameters are only
used when Redis needs to authenticate peer certificates, in one of these
scenarios:
1. Incoming clients or replicas, with `tls-auth-clients` enabled.
2. A replica authenticating the master's peer certificate.
3. Cluster nodes authenticating other nodes when establishing the bus
protocol connection.

The `REDISMODULE_CLIENTINFO_FLAG_SSL` flag was already a part of the `RedisModuleClientInfo` structure but was not implemented.
(cherry picked from commit 64c360c515)
The connection API may create an accepted connection object in an error
state, and callers are expected to check it before attempting to use it.

Adds an `optional` value to the previously boolean `tls-auth-clients` configuration keyword.

This impacts client verification for chained certificates (such as Lets
Encrypt certificates). Client Verify requires the full chain in order to
properly verify the certificate.
This is really required only for older OpenSSL versions.
Also, at the moment Redis does not use OpenSSL from multiple threads so
this will only be useful if modules end up doing that.
This adds support for explicit configuration of a CA certs directory (in
addition to the previously supported bundle file). For redis-cli, if no
explicit CA configuration is supplied the system-wide default
configuration will be adopted.
misc:
- handle SSL_has_pending by iterating though these in beforeSleep, and setting timeout of 0 to aeProcessEvents
- fix issue with epoll signaling EPOLLHUP and EPOLLERR only to the write handlers. (needed to detect the rdb pipe was closed)
- add key-load-delay config for testing
- trim connShutdown which is no longer needed
- rioFdsetWrite -> rioFdWrite - simplified since there's no longer need to write to multiple FDs
- don't detect rdb child exited (don't call wait3) until we detect the pipe is closed
- Cleanup bad optimization from rio.c, add another one
* Introduce a connection abstraction layer for all socket operations and
integrate it across the code base.
* Provide an optional TLS connections implementation based on OpenSSL.
* Pull a newer version of hiredis with TLS support.
* Tests, redis-cli updates for TLS support.
