Motivation:
At the moment why you try to build a SslContext via SslProvider.OPENSSL* and netty-tcnative* is not on the classpath it will fail with:
```
Exception in thread "main" java.lang.NoClassDefFoundError: io/netty/internal/tcnative/SSLPrivateKeyMethod
at io.netty.handler.ssl.SslContext.newClientContextInternal(SslContext.java:830)
at io.netty.handler.ssl.SslContextBuilder.build(SslContextBuilder.java:611)
at io.netty.handler.codec.http.Main.main(Main.java:34)
Caused by: java.lang.ClassNotFoundException: io.netty.internal.tcnative.SSLPrivateKeyMethod

... 3 more
```
We should do better here.
Modifications:
Call `OpenSsl.ensureAvailability()` before trying to construct OpenSsl*Context instances
Result:
More clear error message like:
```
java.lang.UnsatisfiedLinkError: failed to load the required native library
