Standardize and add SSL settings (#213)

This commit reviewed and deprecated the following SSL settings to comply with Logstash's naming convention:
- ssl_enable in favor of ssl_enabled
- ssl_cert in favor of ssl_certificate
- ssl_verify in favor of ssl_client_authentication when mode is server
- ssl_verify in favor of ssl_verification_mode when mode is client

It also added a few SSL configuration validations:
- Added a warning log when ssl_* configs are set but ssl_enabled => false
- ssl_ceritifcate & ssl_key config validation, including checking if both files are readable.
- Ensure no ssl_client_authentication when mode => client
- Ensure no ssl_verification_mode when mode => server
- Ensure an ssl_certificate is provided when mode => server
- Ensure ssl_certificate_authorities is provided when mode => server and it's using the new configuration (ssl_client_authentication)

Fix SSL Subject regression in server mode (#199)

* Fix SSL Subject regression in server mode

Alters the TCP#decode_buffer signature to accept the _ssl subject_ instead of
expecting a ruby socket, so that it can be interoperable between the ruby-based
client mode and the netty-powered server mode.

In server mode, the SSL subject is extracted _once_ when initializing the
connection IFF SSL is enabled and verification is turned on.
