[CL][Internal Review] Add functional to Distribute coins using InternalGauge and External Gauge

[stackman27]

Background

we added the ability to use internal and external gauge in here: #5459. Now it'll be good to have functional testing on it

Invariants to Check

• check if internal gauge are not created when external gauge is expected and vice versa
• check NoLock is only for CL gauges
• check correct emission rate and coins distributed per epoch
• more tbd

Acceptance Criteria

• rigorously test both the flows
• all test should pass without hindering other tests/flow

[p0mvn]

We need to create the following tests:

• Create 2 balancer pools
• Create 2 concentrated pools
• Create 1 external by duration gauge perpetual via MsgCreateGauge
• Create 1 external by duration gauge non-perpetual over 2 epochs MsgCreateGauge
• Create 1 external no-lock gauge perpetual MsgCreateGauge
• Create 1 external no-lock gauge non-perpetual over 2 epochs MsgCreateGauge
• Create distribution records for internal incentives using HandleReplacePoolIncentivesProposal
  • incentivize one of the balancer pools (that is lockable durations associated with them
  • incentivize one of the concentrated pools

Then, let 1 epoch pass artificially. Validate that:

• internal incentives were correctly distributed to the right pool
• external gauge incentives were correctly distributed to the right pools
• IncentivizedPools query returns the right thing
• ExternalGauges query returns the right thing

Next, remove distr records completely using logic in HandleReplacePoolIncentivesProposal

Let the second epoch pass. Confirm that

• only external non-perpetual gauges with 2 epochs distributed
• no internal incentive distribution

Let thing epoch pass. Confirm that:

• nothing distributes as non-perpetual gauges with 2 epochs have ended and perpetual gauges have not been reloaded
