MessagingAccessPoint: "dynamic" vs "static"

cpp impl use dlopen, and java impl use Class.forName for load MessagingAccessPoint lib, go can use plugin to load lib， but it is not common in go community, So I recommend use golang's sql impl style

package management

• go mod（recommend）
• dep

return err instead of throws

do not panic, return err

@llVim For rocketmq/kafka/pulsar MessagingAccessPoint impl, We can put it into other projects for implementation. Currently, this project only focuses on interface.
