Match pallet configuration constants in tests with mainnet #824
Description
Currently the pallet constants are kind of all over the place. Some are set to be for tests only, some for benchmarks only, some for testnet only. If the values change in any one of these instances, it's tough to know what needs to be changed elsewhere.
We should narrow these down to be declared in a single location and imported elsewhere. This could be done either with a single set used everywhere or possibly two, with the other variant being used for testing if it's essential for how the tests function.
