BIP-459: Enable New Tetubal Gauge

[gosuto-inzasheru]

payload for https://forum.balancer.fi/t/bip-xxx-enable-tetubal-20weth-80bal-gauge-polygon/5068

first some dd. given address in the proposal is 0x7342DD5970d9151850386fD4Df286fD85EA4917f

<ethereum>
>>> root = Contract('0x7342DD5970d9151850386fD4Df286fD85EA4917f')
>>> root.getRecipient()
'0xE42d1087c84902cecA43c9887259EB611cfD58cA'
>>> root.getRelativeWeightCap() / 1e18
1.0

cap should be 15% as per request

check if child gauge is configured correctly:

<polygon>
>>> child = Contract('0xE42d1087c84902cecA43c9887259EB611cfD58cA')
>>> child.lp_token()
'0x7aF62C1ebf97034B7542CcEC13a2e79BbcF34380'
>>> lp = Contract(child.lp_token())
>>> lp.symbol()
'tetuBAL-BALWETH'
>>> lp.getAmplificationParameter()
{
    'value': 20000,
    'isUpdating': false,
    'precision': 1000
}

child gauge points to the correct (new) tetu pool with mentioned amp factor of 20

deploy new root gauge, pointing to same child but with 15% cap:

<ethereum>
>>> root_factory = Contract('0xa98Bce70c92aD2ef3288dbcd659bC0d6b62f8F13')
>>> root_factory.create('0xE42d1087c84902cecA43c9887259EB611cfD58cA', Decimal('.15e18'))

root gauge: 0xF6A814eD60653Cb0e36DA247B01E6309318328d4

payload to enable this new root gauge is included in this pr
