Installation: Add more Helm variables

[elliotxx]

What would you like to be added?

Add more Helm variables, example:

• Resources configuration of karpor-server, karpor-sync. Can adapt to some small development machines. karpor-server 添加resources 声明 #518 [Completed]
• Specific image version of karpor-server, karpor-sync deployment 镜像声明优化 #519 [Completed]
• Specific replicas of karpor-server, karpor-sync [Completed]
• Support flexible config storage of etcd, es, such as PVC, hostPath etc. 并非所有用户都有PVC，建议etcd支持hostPath Volume #522 Extend Helm Chart #548 FailedAttachVolume #550
• Support custom fields of service. Extend Helm Chart #548
• ......

Why is this needed?

Add more Helm variables to improve installation flexibility and adapt to more installation scenarios.

@T1-leiyang Thanks for your enthusiasm! 🔥 But I have already started working on this issue. Maybe I can wait for you to complete the #461 , let's complete other tasks of this issue together.

@T1-leiyang Hi, I have preliminary optimized the Helm Chart in the following work. Currently, these variables are supported, but they may not be sufficient. If you are willing, you can add more variables on this basis:

• feat: refact karpor chart, add more variables, bump to v0.5 charts#36
• feat: support specify registry proxy in karpor chart charts#37
• feat: support custom replicas and resources in karpor chart charts#38

@danielstankw Yeah, I am now debugging another feature #497 . The optimization (PVC, StorageClass, Service ...) of Helm Chart originally planned to start later this week. But if you can help optimize it, it will be great!

@elliotxx can you direct me where can I find the src for the helm chart so that I can fork it ?

@danielstankw Oh, sorry, the chart repo is here: https://github.com/KusionStack/charts/tree/master/charts/karpor
