Add MaxTipAmount for pallet-tips (#1709)

Browse Source 
Last week we experienced a governance attack.
Surprisingly, there was no upper limit on the tip amount.

Due to the mechanism of pallet-fragment-election, the council members
will be refreshed immediately. Attacker is easy to control the council
and give a large tip amount.
