1. Clearly separate the log messages from any fields that are
captured. The log message itself should be meaningful because it
depends on the underlying formatter, how/if the fields are displayed.
2. Some log messages had very little context, expand that.
3. Wording of errors was inconsistent, hopefully all errors should
now start with `Failed to ...`.
4. Some log messages were duplicated across multiple layers (like opening
the database).
5. Some log messages were split into two where one part is now an `error!`
and the 2nd part is an `info!` on what is happening next.
6. Where appropriate, punctuation has been removed to not interrupt
the reader's flow.
This reduces the overall amount of LoC that imports take up in our
codebase by almost 100.
It also makes merge-conflicts less likely because there is less
grouping together of imports that may lead to layout changes which
in turn can cause merge conflicts.
Hence, reducing complexity of the codebase. Note that the seed will be
used by both nectar and the cli whereas the config mod will be different
so this changes helps with the next step of having a dedicated config
module for each binary.
This includes the introduction of the --data-dir parameter instead of the --database.
Both the seed file and the database are stored in the data-dir, the database in sub-folder `database`.
