Problem Definition

Refer: Finschia/cosmos-sdk#1

Work Breakdown

• Delegate native logics to Finschia/cosmos-sdk #1204
• Update x/collection to use Finschia/cosmos-sdk@v0.50.2 #1196
• Update x/foundation to use Finschia/cosmos-sdk@v0.50.2 #1197
• Update x/stakingplus to use Finschia/cosmos-sdk@v0.50.2 #1200

• Update migration from Finschia/finschia-sdk v0.48.x
• Stop using of x/params in x/foundation #1232
• Use x/collections (c.f. not x/collection, it's cosmos native feature) in x/foundation
• Apply necessary PRs from the finschia-sdk triage

The works would be first merged onto a feature branch bumpup50. After finishing internal audit, it would be finally merged onto main.
