Node should not allow feeless report transaction with an unreasonable gas limit

Describe the bug
When delegating to a validator, there is no validation for the input to take into account the transaction fees. It is possible to submit a transaction that will definitely fail and cost the user the transaction fee.

To Reproduce
Steps to reproduce the behavior:

1. Sign in to an account.
2. Go to validator page.
3. Click on 'Delegate'.
4. Enter the amount as equal
