Merge #2451

2451: Use env_logger instead of flexi_logger r=matklad a=AlexanderEkdahl

This fixes https://github.com/rust-analyzer/rust-analyzer/issues/2335

- By default only `error` will be printed. From what I can tell this matches the current behaviour. Configured through `RUST_LOG`.
- I looked through the optional dependencies for `env_logger`and I have only enabled `human_time`. Without this feature no timestamp will be shown for log messages.
- `RA_LOG_DIR` feature is removed

This PR adds 2 new dependencies(`env_logger` and `human_time`) and removes 6 dependencies.
