Fix issue with sslCA driverOption

[edvardpotter]

When I set sslCA in driverOptions like this:

clickhouse:
                host:     '%host%'
                port:     '%port%'
                user:     '%username%'
                password: '%password%'
                dbname:   '%name%'
                driver_class: FOD\DBALClickHouse\Driver
                wrapper_class: FOD\DBALClickHouse\Connection
                options:
                    enable_http_compression: 1
                    max_execution_time: 60
                    sslCA: '/usr/local/share/ca-certificates/Yandex/YandexInternalRootCA.crt'
                    https: true

I get the next error (Unknown setting sslCA):

bin/console doctrine:migrations:migrate --em=clickhouse --configuration=./app/config/migrations/doctrine_migrations_clickhouse.yml --no-interaction

In DBALException.php line 172:

  IN:SELECT database, name FROM system.tables WHERE database != 'system' AND engine != 'View' FORMAT JSON

This happen because sslCA passed in URI

https://somecluster.yandex.net:8443?extremes=0&readonly=2&max_execution_time=60&enable_http_compression=1&database=db1&sslCA=%2Fusr%2Flocal%2Fshare%2Fca-certificates%2FYandex%2FYandexInternalRootCA.crt

and clickhouse return this error:

Code: 115, e.displayText() = DB::Exception: Unknown setting sslCA (version 20.12.3.3 (official build))

Also for this parameter to work, it must be passed in \ClickHouseDB\Client::__construct(connectParams)

(currently it passed in \ClickHouseDB\Client::__construct(settings)).

I fixed this issues in my fork.
