[BUG] `HATCHET_CLIENT_LOG_LEVEL` is unused

[gregfurman]

Describe the issue

When running a hatchet task via the client, setting the HATCHET_CLIENT_LOG_LEVEL has no effect on the log level or format.

While the docs indicate that the worker's log level is INFO and can be configured i.e

hatchet/frontend/docs/pages/self-hosting/worker-configuration-options.mdx

Line 47 in 871d63d

| `HATCHET_CLIENT_LOG_LEVEL` | Log level for the worker | `INFO` |

The log level defaults to DEBUG and is always in JSON format due to NewDefaultLogger always being used to set the default logger.

hatchet/pkg/client/client.go

Line 132 in 22fd98e

logger := logger.NewDefaultLogger("client")

The solution here is instead, to attach a shared.LoggerConfigFile to the client config and pass it to a logger.NewStdErr.

Environment

• SDK: Golang v0.78.22

Expected behavior

The log level (and optionally the format) should be configurable via environment variables or config.

Code to Reproduce, Logs, or Screenshots

Run the simple workflow in examples/go/simple against a hatchet instance.

$ env $(cat .env | xargs) HATCHET_CLIENT_LOG_LEVEL=warn go run main.go

See how the client logs are at the debug level despite HATCHET_CLIENT_LOG_LEVEL=warn
