[services] introduce sonic.target (#5705)

- Why I did it
Group all SONiC services together and able to manage them together. Will be used in config reload command as much simpler and generic way to restart services.

- How I did it
Add services to sonic.target

- How to verify it
Together with Azure/sonic-utilities#1199
config reload -y
