Staking pair with no bonding period

[Buckram123]

Adding no bonding staking pair to wyndex-bundle:

• Added abstr token
• Added abstr-usd pair and pool
• Added one small test of it

Closes AbstractSDK/integration-bundles#27

Note: period is 0 instead of None, don't think we want to change this method https://github.com/AbstractSDK/abstract/blob/main/integrations/wyndex/packages/wyndex-adapter/src/staking.rs#L244-L253

@Buckram123 thanks for this effort!

There is just one issue im having and that is that the stakingInfo for that pool still returns a unbonding period being Some(Time(0)). In our contract, we assume that a zero unbonding period is a none, which imo makes the most sense. I just adjusted one of our ignored tests to use the abstr_usd pool using this branch as a dependency, however It then returned a the Some(...) instead of None.

The staking ingo response is defined to have an optional unbonding_periods variable which is what we base instantiate logic upon.

abstract/framework/packages/staking/src/msg.rs

Lines 134 to 139 in 82ced8a

	pub struct StakingInfoResponse {
	pub staking_target: StakingTarget,
	pub staking_token: AssetInfo,
	pub unbonding_periods: Option<Vec<Duration>>,
	pub max_claims: Option<u32>,
	}

I guess we can adjust the contract a bit so that it handles the Time(0) case.

[MbBrainz]

So only thing im worried about is the fact that an unbonding_period of Some(Time(0)) might still require us to call unbond AND claim on the staking api. The current impl enables us to distinguish this case by having None or Time(>0).

[Buckram123]

It will require to implement and maintain astropot bundle, which we locally decided would be overhead at this point. Closing it right now until we decide it's really necessary. Please don't delete a branch yet
