This might make one think that we are being outrageously strict,
but at the end of the day, it can help investigate crashes
or inspect logs without artwork all over the place.
Following some discussions, the `user` mode was renamed to `dev`
mode.
This commit also upgrades some deps, other than clap which has
deprecated yaml support (we will continue to use 2.x).
Finally, the CHANGELOG was updated.
* Enable maximum connections to be configured
* Add arbiter for handling server startup
* Add handling of maxcon for command-line args
* Add changelog entry
* Stop accepting writes if snapshotting fails
This is an important consideration: if BGSAVE fails and poisons the
database, snapshotting can and should too. But this is debatable in some
parts. For example, users may configure snapshots to be on a network
file system (symlinked maybe) and this can fail.
Now in some cases, this failure 'may be acceptable'. This commit adds a
way to customize this behavior through the `failsafe` key in the
snapshots section of the cfg file and through the --stop-write-on-fail
option passed to `skyd` on startup. However, BGSAVE remains unchanged:
it will always poison the database if it fails. If the user doesn't want
this, they can simply disable BGSAVE.
* Add changelog
This closes#107, closes#108 and closes#109.
The configuration template was updated to include TLS/SSL and the
corresponding tests were also updated.
It also renames `sdb` to `skyd` for streamlining binary names.

Also, dependencies were upgraded across all crates and the version for
`tdb-macros` was streamlined to 0.5.0 like the other crates.

There is no merit in having a redundant `enabled` key under
`snapshot` in the configuration file; if a `snapshot` key is present,
it is inherently obvious that snapshotting is enabled
