shared configuration / properties / ENV variables for CI & CD.

[tarunptala]

Summary

can we have support for shared config / properties / env variable for CI & CD. currently, we have to define these properties for each application separately in devtron which creates unnecessary duplicate entries. There are use cases when you would like to use same variable/property across CIs just like many use with Jenkins or alternatives.

https://docs.devtron.ai/user-guide/creating-application/environment-overrides

Unnecessary definition of property/variable for each app. - duplication.

Motivation

To avoid duplicate entries at multiple CIs.

Proposal

Shared ENV overrides for Apps should be able to address this.
