fw/parsers: Ensure plug-in names are converted to an identifier

Ensure that a plug-ins config entry is converted to an identifier before being
stored in the PluginCache so that the relevant configuration can be
retrieved appropriately. For example this allows for both 'trace-cmd' and
'trace_cmd' to be used as config entries to provide configuration for the
'trace-cmd' plugin.
