how to implement the feature of cipher plugin in service-center?

[zhaoqi211]

Describe the bug
When I use tls feature in service-center(Reference Example of plugin.md -> # Plug-in mechanism), I got an error of,
ERROR plugin/loader.go:53 no any plugin has been loaded {"error": "load plugin 'cipher' error for plugin: not implemented"}

To Reproduce
Steps to reproduce the behavior:

1. create a go file to implement the Cipher interface

package main

func Encrypt(src string) (string, error) {
        return src,nil
}
func Decrypt(src string) (string, error) {
        return src,nil
}

2. compile go file to generate so

GOPATH=go build -o cipher_plugin.so -buildmode=plugin cipher_plugin.go

3. move the cipher_plugin.so to plugins directory
4. restart service-center and then I see error

If I remove the cipher_plugin.go from plugins dir, and with plaintext password in cert_pwd file , The tls feature is normal

Expected behavior
A clear and concise description of what you expected to happen.
