Description

After submitting https://github.com/apache/zookeeper/pull/1107 about SSL support in ZooKeeper C client, ztzg shared some very good improvement ideas, so we will now:

• use the --with-openssl autoconf argument in the same way as SASL is doing (i.e. by default we autodetect the openssl library, but with the option we can turn off SSL or specify a custom location for openssl lib)
• we will add and document a custom maven parameter that will be used during the c-client build
• we will also try to make the same logics during the windows build (cmake)
