Support custom keystore

[pjuarezd]

Problem

Complementary PR for the Issue Support for custom truststore at Connector level #546

Solution

Add the following connector settings:

ssl.truststore.location
ssl.truststore.password
ssl.truststore.type

Via this settings will be possible include additional certificates to the trustchain by storing them in a keystore file, so that private CA root certificates and Self-signed certificates are supported.

Does this solution apply anywhere else?
