Add a manual balance entry

Manually adjust the available balance on a commit or credit. This entry is appended to the commit ledger as a new event. Optionally include a description that provides the reasoning for the entry.

Use this endpoint to:

• Address incorrect usage burn-down caused by malformed usage or invalid config
• Decrease available balance to account for outages where usage may have not been tracked or sent to Metronome
• Issue credits to customers in the form of increased balance on existing commit or credit

Usage guidelines:

Manual ledger entries can be extremely useful for resolving discrepancies in Metronome. However, most corrections to inaccurate billings can be modified upstream of the commit, whether that is via contract editing, rate editing, or other actions that cause an invoice to be recalculated.
