This adds a `parse-bucket-logs.{service,timer}`, running once every
night at 3AM UTC, figuring out the last time it was run and parsing
bucket logs for all previous days.
It invokes the `archeology-parse-bucket-logs` script to produce
a .parquet file with the bucket logs in `s3://nix-cache-log/log/` for
that day (inside a temporary directory), then on success uploads the
produced parquet file to
`s3://nix-archeologist/nix-cache-bucket-logs/yyyy-mm-dd.parquet`.

This adds a `archeology-parse-bucket-logs` CLI tool to `$PATH`.
It can be invoked like this:
```
archeology-parse-bucket-logs http://nix-cache-log.s3.amazonaws.com/log/2023-11-10-00-* bucket_logs_2023-11-10-00.pq.zstd
````
… and will produce a zstd-compressed Parquet file for (roughly) that
time range.
As the EC2 instance credentials don't give access to the logs bucket
(yet), other AWS credentials need to be provided.
This can be accomplished by using "AWS_ACCESS_KEY_ID",
"AWS_SECRET_ACCESS_KEY", "AWS_SESSION_TOKEN" from
"Option 2: Manually add a profile to your AWS credentials file (Short-
term credentials)" in AWS IAM Identity Center.
Processing logs for a one-hour range takes a minute or two, the
resulting zstd-compressed Parquet file is around 40-80M in size.
Processing logs for a whole day takes some 25mins, due to the sheer
amount of data (12 GB of raw log data, distributed among 450k individual
files, 20Mio log lines), but at least clickhouse isn't able to parse the
resulting parquet file back in:
> Code: 36. DB::Exception: IOError: Couldn't deserialize thrift: MaxMessageSize reached
For future automation tasks, it's probably better to run this once an
hour, and further join the data later on.

This adds a deploy-archeology script.
I tried getting morph to work first, but passing it a
depot.ops.nixos.nixosFor seems to be very hard - the NixOS module system
doesn't like the arguments it's called with.
Replace morph with a 3 line bash script, which assumes your ssh_config
contains config for an `archeology` host.
