fix: setup price list import

[srindom]

What

• Adds a batch job strategy that can handle importing prices to a PriceList
• The import format is:

Product Variant ID	SKU	Price {currency code}	Price {region name} [{currency code}]	...
variant_1234		32.53	123.20
	MY-PROD-BLUE	44.32	42.22

• Each row must either have a Product Variant ID or SKU (variant ID takes precedent).
• Currency prices are entered in human format (i.e., as decimals) (this PR introduces computerizeAmount utility to convert human format to DB format)
• PR also makes changes to product import to make sure pricing import formats are aligned
• Adds a clearPrices method in the PriceListService that can be used to delete all prices in a price list.

Usage

POST /admin/batch-job
{
  context: {
    fileKey: "import.csv",
    price_list_id: "pl_my_id",
  }
}

Note: the import strategy will delete all existing prices in the price list, before creating the prices as specified by the import file.

Testing

• Integration test for importing price list prices; covers case with
  • Price based on Variant ID
  • Price based on SKU
  • Non-division and division currencies (USD, EUR, JPY)
  • Currency and Region price
  • Trimming of headers in import
• Integration test for failed import due to invalid format
  • Checks that error is stored in batchJob.result.errors

Fixes CORE-590
