#### Problem
Our existing datapoint macro syntax does directly not support group-by tags.
The existing workaround is to embed the group-by tags into the metric name which does not scale well.
#### Summary of Changes
This PR extends the existing syntax to support group-by tags as follows. The new syntax is also compatible with the existing syntax:
```
datapoint_debug!(
"metric_name",
"tag" => "tag-value",
"tag2" => "tag-value2",
....
("field1", 100, i64), // field syntax is the same as the current syntax.
("field2", "hello", String),
...
);
```

Previously, running the tests with RUST_LOG=none would fail, because the
env logger would set its filter level to reject all log messages, and
incrementing a counter only happens if the global logger has at least
the specified log level. Having the tests behave differently when
RUST_LOG is set is surprising, they should be self-contained.
Nix' buildRustPackage sets RUST_LOG="" to make the build logs less
verbose. I have trouble packaging Solana for Nix because of this, and I
believe making the tests independent of the environment is a good
solution for this.
