Ticket 47699: Propagate plugin precedence to all registered function types

Bug Description:
	A plugin can define its nsslapd-pluginprecedence (config), that is number that order the
	plugins in the plugin list.
	If a plugin register an other plugin (slapi_register_plugin), this number is not
	preserved in the new plugin and it gets a default plugin precedence value.

Fix Description:
	When registering a plugin (slapi_register_plugin) a plugin identity is provided that
	contains the original plugin configuration (with its precedence).
	The fix consist to set (in slapi_register_plugin_ext ) the precedence to the
	value store in the plugin identity. It is done in slapi_register_plugin_ext
	because referencial integrity calls directly slapi_register_plugin_ext.
