Remove unneeded dependencies and dev-dependencies. Made self_destruct test not dependent on wasm bin size. Updated code related to deprecated warning on tracing-subscriber `scope()` ( See https://github.com/tokio-rs/tracing/issues/1429 )
Substrate tracing primitives and macros.
To trace functions or individual code in Substrate, this crate provides [within_span]
and [enter_span]. See the individual docs for how to use these macros.
Note that to allow traces from wasm execution environment there are
2 reserved identifiers for tracing Field recording, stored in the consts:
WASM_TARGET_KEY and WASM_NAME_KEY - if you choose to record fields, you
must ensure that your identifiers do not clash with either of these.
Additionally, we have a const: WASM_TRACE_IDENTIFIER, which holds a span name used
to signal that the 'actual' span name and target should be retrieved instead from
the associated Fields mentioned above.
