RtApi - Pallet Loans Extended

[mustermeiszer]

Description

There are multiple things the loans runtime api should expose, besides the current fetching of asset informations.

• RtApi - Max borrow amount #793
• RtAPI - PV of a Loan #942
• RtApi - PoolValuation RuntimeApi and RPC Method #750
• feat: Rt-Api pallet-loans - Unify External- and Internal-Pricing #1675

Research/based on

UI needs and subgraph indexer needs

How will this affect the code base

• Ease external integrations

Tasks

• Notify Embrio about the changes and the possibility to already use the unification of external- and internal-pricing in the indexer (probably ping @hieronx or @mustermeiszer to channel this to embrio)

Update:

• RtApi - Max borrow amount #793: Not done, but can be done fastly.
• RtAPI - PV of a Loan #942: Done (see PR comment)
• RtApi - PoolValuation RuntimeApi and RPC Method #750: Partially done (see PR comment)
• feat: Rt-Api pallet-loans - Unify External- and Internal-Pricing #1675: Not done, but I think this is can not be ready for the next RU. It's a Loans V4 refactor.
