Scylla cluster starts before server properties are read

[VladyslavKurmaz]

Issue

Server doesn't use Scylla server DNS name from the config.properties.
Whatever Scylla DNS is defined, server will use localhost

server_1    | com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: localhost/127.0.0.1:9042 (com.datastax.driver.core.exceptions.TransportException: [localhost/127.0.0.1:9042] Cannot connect), localhost/0:0:0:0:0:0:0:1:9042 (com.datastax.driver.core.exceptions.TransportException: [localhost/0:0:0:0:0:0:0:1:9042] Cannot connect))
server_1    |   at com.datastax.driver.core.ControlConnection.reconnectInternal(ControlConnection.java:232)

Environment

• Ubuntu 16.04

# java -version
openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-0ubuntu1.16.04.2-b11)
OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)

Root cause

Scylla cluster starts before server reads properties from config.properties file.

Workaround

Hardcode Scylla server DNS name
server/src/main/java/ua/papka24/server/db/scylla/ScyllaCluster.java
ln 82

this.scyllaPath = "scylla";//scyllaPath;
