Bug - Hardcoded SSH key file

[akshita-sukhlecha]

In the upload_status method in ppss file :

The SSH-key file is hardcoded as ppss-key.dsa :
scp -q -o GlobalKnownHostsFile=./known_hosts -i ppss-key.dsa $NODE_STATUS_FILE $USER@$SSH_SERVER:$PPSS_HOME_DIR/$PPSS_NODE_STATUS/

The key should instead be provided using the $SSH_KEY variable :
scp -q -o GlobalKnownHostsFile=./known_hosts $SSH_KEY $NODE_STATUS_FILE $USER@$SSH_SERVER:$PPSS_HOME_DIR/$PPSS_NODE_STATUS/
