Requirements: make the plugin for DevLake production-ready.

For example:

• use a helm chart to manage DevLake installation instead of YAML
• use Go helmclient to install instead of kubectl apply
• adjust the amount of numbers of pods of all the deployments so that there is no single point of failure and enough redundancy
• MySQL persistent storage. Local, or other storage? If local, make sure that deleting the MySQL pod won't lose any data.
• Other improvements, for example, add more parameters so that the usage of the plugin can be customized.
