`STREAM_CLIENT_PERSISTENT` does not work in conjunction with `useSsl => true`

[particleflux]

Custom socketClientFlags with the STREAM_CLIENT_PERSISTENT flag set will not work with useSsl => true, due to attempting to re-enable encryption when it is already active.

Could probably check for the persistent flag in the bitmask and skip the SSL init conditionally.
Not that simple, as it could be an already open connection or a fresh one.

What steps will reproduce the problem?

Have a redis connection configured with:

'hostname' => '<your-redis-host>',
'port'     => '6379/sessions',
'database' => 2,
'useSSL'   => true,
'socketClientFlags' => STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT,

and do multiple requests.

What's expected?

Connection is reused successfully.

What do you get instead?
