feat: add plugin zentao

[xavier-hou]

Pre-Checklist

Note: please complete ALL items in the following checklist.

• I have read through the CONTRIBUTING.md documentation.
• My code has the necessary comments and documentation (if needed).
• I have added relevant tests

Description

Add zentao plugin, currently just deal with zentao installation.

For this implementation zentao application is deployed in a k8s cluster by client-go, later I expect to deploy zentao by Helm.

Implementation

1. create.go

Create zentao namespaces, persistentVolume, persistentVolumeClaim, deployment, service.

• PersistentVolume use HostPath and in a single-node cluster now.
• Service is exposed by NodePort.

2. delete.go

Delete zentao namespaces, persistentVolume, persistentVolumeClaim, deployment, service.

• Perform the opposite operation of creation.

3. k8s.go

Some cluster-related operations

4. update.go

Just rebuild zentao deployment and service.

Options and configuration

Here needs more advice and consideration. I want to support different installation way in config files and use type field to indicate.
A simple example configuration file is as follows:

tools:
  # name of the tool
  - name: zentao
    # id of the tool instance
    instanceID: default
    # format: name.instanceID; If specified, dtm will make sure the dependency is applied first before handling this tool
    dependsOn: [ ]
    # options for the plugin
    options:
      type: "clientAPI"
      clientAPI:
        namespace: "zentao"
        storageClassName: "zentao-storage"
        persistentVolume:
          zentaoPVName: "zentao-pv"
          zentaoPVCapacity: "1G"
          mysqlPVName: "mysql-pv"
          mysqlPVCapacity: "1G"
        persistentVolumeclaim:
          zentaoPVCName: "zentao-pvc"
          zentaoPVCCapacity: "1G"
          mysqlPVCName: "mysql-pv"
          mysqlPVCCapacity: "1G"
        deployment:
          name: "zentao-dp"
          replicas: 3
          image: "easysoft/zentao:latest"
          mysqlPasswdName: "MYSQL_ROOT_PASSWORD"
          mysqlPasswdValue: "1234567"
        service:
          name: "zentao-svc"
          nodePort: 30081
      helm:

By the way, I am not particularly satisfied with the current implementation, I need more requirements and suggestions.

Please feel free to give me any advice you think would make sense, I would really appreciate it!

I used your code for a local test, and it can run well. It's good that you try to specify the deployment method through configuration. Documents can be completed. @HXCGIT

/hold
I'll check the code again and add plugin docs.

It seems MySQL is a requirement for zentao. Do you think it's possible to install MySQL as well? @HXCGIT @daniel-hutao @KeHaohaoke

[xavier-hou]

@IronCore864 Yep, Zentao need MySQL.

1. For official images easysoft/zentao, zentao service and mysql service are all installed. https://www.zentao.net/book/zentaopmshelp/405.html
2. I'm not exactly sure what you mean. If we use a individual mysql service in another pod, we will need to modify some initialization scripts of the official image accordingly.

@KeHaohaoke @daniel-hutao any good ideas?

[xavier-hou]

By the way, the official image doesn't seem to work well in mac m1 arm. Please test in linux amd64 system.

How to reopen this pull request?

@KeHaohaoke @IronCore864 PTAL.

[KeHaohaoke]

Zentao's official image integrates MySQL, so we discuss that we can use the official image first. That's ok. @HXCGIT

@HXCGIT thanks for this great contribution. I'll test it locally and get back to you ASAP.
