Alexander Theißen 6863476603 contracts: Add storage deposits (#10082)
* Frame no longer needs to be mutable (refactoring artifact)

* Remove Contract/Tombstone deposit

* Add StorageMeter

* cargo fmt

* Fix weight annotation

* cargo run --quiet --release --features=runtime-benchmarks --manifest-path=bin/node/cli/Cargo.toml -- benchmark --chain=dev --steps=50 --repeat=20 --pallet=pallet_contracts --extrinsic=* --execution=wasm --wasm-execution=compiled --heap-pages=4096 --output=./frame/contracts/src/weights.rs --template=./.maintain/frame-weight-template.hbs

* Simplify keep check for contract accounts

- Make sure that the "base deposit" for each contract >= ed
- Remove now obsolete checks when sneding away free balance

* Remove unused imports and functions

* Rename storage_limit to storage_deposit_limit

* cargo fmt

* Fix typo

Co-authored-by: Michael Müller <michi@parity.io>

* Finish up rename of storage_limit

* Fix rpc tests

* Make use of `StorageDepositLimitTooHigh`

* Add tests and fix bugs discovered by tests

* Add storage migration

* Don't use u128 in RPC

* Fix weight of migration

* Rename `endowment` to `value`

* Fix bug where contract couldn't get funded by a storage deposit

- Make sure that contract gets funded from deposits before value is transferred
- Don't reserve value at origin because otherwise funding isn't possible
	- Just transfer free balance and reserve it after the transfer
- When refunding make sure that this refund can't dust the contract
	- Can only happen after a runtime upgrade where costs where upped
- Add more tests

* Apply suggestions from code review

* Remove unused `fn storage_meter`

* Fix copy pasta doc error

* Import `MaxEncodeLen` from codec

* Beautify RPC trait bounds

* Add re-instrument behaviour to dispatchable doc

* Make sure a account won't be destroyed a refund after a slash

* Apply suggestions from code review
