* Deter other processes from using the same data dir
For more information, see #167
* Don't lock `pid_file`
Windows has mandatory locking so second instance won't be able to read
the PID of the other process. We'll just keep the file descriptor/handle
open

## Unreleased
### Fixes
- The save operation now automatically attempts to recover on failure during termination [see [#166](https://github.com/skytable/skytable/pull/166)]
- More than one process can no longer concurrently use the same data directory, preventing any possible data corruption [see [#169](https://github.com/skytable/skytable/pull/169), [#167](https://github.com/skytable/skytable/issues/167)]
