feat(state)!: Adding fee parameter to CoreAccessor operations

[distractedm1nd]

Overview

Adding fee parameter to CoreAccessor operations.

All transaction endpoints now have a "fee" key needed in the JSON request. An example value for this can be 2000. This includes the following endpoints:

• SubmitPayForData
• Transfer
• Delegate
• BeginRedelegate
• Undelegate
• CancelUnbondingDelegation

After this change, a new field is added to the json requests in the gateway:
{oldRequest..., "fee": 2000}

LGTM, the only concern I have is bloat of params, which we can fix later by passing some of the optional params as a structure(JSON RPC lib allows that). Very low prio rn to even care, but still
