Request to enable function level logging for function load

#### What problem would the feature you're requesting solve? Please describe.
Currently function specific logging requires function invocation id to retrieve logger for a function and perform function specific logging, and since at function load time there's no invocation id available, so at this point it's not possible to write function specific log in the function level logger

#### Describe the solution you'd like
Please allow writing function load logs in the function specific log

No files, tests, or entry points are named in the issue. Start by tracing how function-load logging obtains a function-specific logger and how invocation IDs are required, then determine the expected behavior and tests for logging before an invocation exists.
