Let the StorPool CLI prompt be customized using the SP_CLI_PROMPT variable
Use port 443 (instead of 8086) in the storpool_stat service to get through firewalls more easily
Add support for GCC 7

Bridge redundancy, now multiple bridges may run at the same time with only one active at a given time
Bridge lower CPU when recovering objects with very small amount of actual data
Improve the site-to-site throughput on higher-latency connections
Support 4.15+ kernels and gcc 7
Let the configuration in /etc/storpool.conf.d/*.conf override the one in /etc/storpool.conf
