feat(mojaloop/#2880): simplify liquidity cover check and fix issue with validation - mojaloop/project#2880
- fixes to collections/hub/golden_path/feature_tests/block_transfers
  - aligned liquidity and position calculations with central-ledger logic
  - cleaned up unecessary requests (i.e. why have two requests to fetch settlement and position accounts when it can be done in one?)

- cleaned up test-scripts, and aligned them to central-ledger changes
- added new env var environment.SETTLEMENT_RULE_INTERCHANGE_FEE which defaults to '0.006' (ref: https://github.com/mojaloop/central-settlement/blob/master/scripts/transferSettlementTemp/interchangeFeeCalculation.js#L47)
- updated script logic to correctly calculate interchange-fees based on the provided environment.SETTLEMENT_RULE_INTERCHANGE_FEE

- re-factored `[new sims] transfers, positions CGS Window1 tests (OTC-649, OTC-645)`
  - standardised naming convention
  - re-aligned position, settlement and interchange checks, and expanded on checks dynamically based on the transfer amounts (Tx1, Tx2, Tx3, Tx4, Tx5, Tx6) instead of using "hard-coded" values
  - added new OPTIONAL env vars for:
    1. SETTLEMENT_CGS_TX_AMOUNT_1 (defaults: 15), SETTLEMENT_CGS_TX_AMOUNT_2 (defaults: 87.88), SETTLEMENT_CGS_TX_AMOUNT_3 (defaults: 158.36), SETTLEMENT_CGS_TX_AMOUNT_4 (defaults: 211.11), SETTLEMENT_CGS_TX_AMOUNT_5 (defaults: 14.05), SETTLEMENT_CGS_TX_AMOUNT_6 (defaults: 150) representing the transfer amounts for each Transaction. These correlate to Tx1...Tx6
    2. SETTLEMENT_RULE_INTERCHANGE_FEE (defaults: 0.006) which is the Interchange Fee % used to calculate the aggregate Fee

…hecks) and fixed test-case naming/meta-data

- removed duplicate test-cases
- fixed names for consistency

…es into feat/#2880-Simplify-liquidity-cover-check-and-fix-issue-with-validation

- added p2p happy path with balance checks (position, settlement, and reserved balances)
- fixed issue in block transfers to ensure that the amount removes trailing spaces by converting a number converted to a fixed string back into a number to drop any trailing zeros: Number(Number.toFixed(2))
- updated some descriptions/meta for newsetcgs test-cases

…case

- added funds-in for testfsp's 1,2,3 and 4
- added new optional environment parameters for each testfsp: SETTLEMENT_CGS_FUNDSIN_TESTFSP1, SETTLEMENT_CGS_FUNDSIN_TESTFSP2, SETTLEMENT_CGS_FUNDSIN_TESTFSP3, SETTLEMENT_CGS_FUNDSIN_TESTFSP4 - with defaults of 2000

- check to see settlement-balance has increased by the funds-in amount for testfsp 1, 2, 3 & 4

- disabled duplicate Get Balance requests for CGS tests, and added comment indicating that they are disabled by default but useful for debugging issues.

- removed duplicate tests (possible bug in TTK)

This reverts commit 9304fa9.
