Plugin Config

Allow plugins to have configs. When logging syscalls we hardcode our target binary. We could support more than one binary, change binary on the fly, even have a follow children option.

Have a default config for a plugin then a way to read and write the plugin from the CLI.

Start by locating how plugins currently log syscalls, where the target binary is hardcoded, and which CLI entry points exist. Clarify the plugin config format and runtime behavior; done should include default plugin configuration, CLI read/write support, and the requested multiple-binary, dynamic-target, and follow-children options.
