Use DBConnectionURI directly (#833)

This commit changes yorkie-cluster chart to allow direct input of the
DBConnectionURI.

Users can set options such as authmechanism in the MongoDB Connection
URI. However, the current chart separates port and URI, making it
impossible to configure settings. This commit enables users to
directly set DBConnectionURI, allowing them to specify options when
connecting to MongoDB.
