Observable - Addition of price sub types

Background

The PriceSchedule offers a priceType which can be used to specify what type of price this is e.g. InterestRate, AssetPrice. In certain scenarios more granularity is required.

For example, when defining a price as an "InterestRate" on a securities lending trade, we need to be able to further identify if this is a lending fee or a rebate rate.

What is being released?

The key changes are:

• A new PriceSubTypeEnum has been created that holds the same options as CashPriceTypeEnum but with the addition of the "Rebate" option.
• A new optional attribute priceSubType of type PriceSubTypeEnum has been added to PriceSchedule
• The PriceSchedule -> cashPrice attribute has been removed as it is not required in the context of a PriceSchedule.
• The premiumType attribute, previously under cashPrice -> premiumExpression, has been added directly under PriceSchedule.
• The functions that create new Price items have been updated to remove cashPrice and include priceSubType
• The functions updated were:
  • Create_StockSplit
  • Create_OnDemandRateChangePriceChangeInstruction
  • Create_RepricePrimitiveInstruction
  • Create_AdjustmentPrimitiveInstruction
  • ResolveEquityInitialPrice
• The Ingest functions have been updated to reflect the changes too.

Note that the existing CashPrice and CashPriceTypeEnum are still used by transfers. They will remain in the model for now and their usage will be reviewed further in #4195

Extensive analysis and review was performed in order to define these changes. For full details please refer to the Issue #3871

Review Directions

Changes can be reviewed in PR: #4207

What is being released?

Updated to remove CashPriceTypeEnum as this is only used by the CashPrice. Within CashPrice the cashPriceType was updated to now be priceSubType of type PriceSubTypeEnum. The condition that used cashPriceType was also updated to reflect this name change.
