[resource_detectors] implementation of a scrub for sanitisation of sensitive data of process.command_args

[nikhilbhatia08]

As per the semconv we need to sanitize sensitive information of process.command_args and process.command_line. So one strategy could be that we could give user the control of doing that by giving the user to provide a list of args that the user wants to be scrubbed or hidden.

For example the command_args are : ["--PASS=some_value", "--ARG2=some_val", "--SECRET_KEY=secret"]

Then the user can provide a list what needs to be scrubbed: {"PASS", "SECRET_KEY"}

Then the user would get a list of : ["--PASS=*", "--ARG2=some_val", "--SECRET_KEY="]

How is this idea?
