param migration (params module is deprecated in sdk0.47)

[yaruwangway]

Summary

Gaia v10 will use sdk 0.47.

In sdk0.47, params store is deprecated, in favour of each module housing its own parameters. All the params in params module need to be migrated. migration example
Besides, params holding in params module need to migrate to the sdk modules, params module also holds globalfees params, so globalfees params need to migrate to global fees module.

Problem Definition

Proposal

The following steps need to be done:

bank, gov, etc params migration

• all the params in the params store need to be migrated, call the migration in upgrade handler. (if the params module is sdk module)

globalfee params migration

• add set params in globalfee module, example
• migrating the value from params store to globalfee store, example
• change the fee antehandler to get data from globalfee store rather than params store, example.
• call the migration in upgrade handler (version map)
