missing providing other TLS truststore than default java one

For TLS, actual implementation either use the default truststore or using the server certificate provided by option `serverSslCert`.

MySQL permit another option, to use another truststore. This is done using options `trustCertificateKeyStoreUrl`/`trustCertificateKeyStorePassword`.

For compatibility, this has to be added.

This can just be use using option:
"jdbc:mariadb://host/db?trustCertificateKeyStoreUrl=/path/to/trustStore"

default truststore /lib/security/jssecacerts will then not be used, only the one in parameter.
Option trustCertificateKeyStorePassword can be set for jks truststore that can have a password.
