/**
 * Each entry in a har file is supposed to have a corresponding unique key (a string).
 * The har key manager is both a getter and a setter for the key of an entry.
 *
 * @remarks
 *
 * The har key manager is a function that is called either to get the key of an entry (when
 * the key parameter is undefined) or to set it (when the key parameter is defined).
 *
 * It should not modify the entry when the key parameter is undefined.
 *
 * When the key parameter is defined, the har key manager is supposed to change the provided entry, in order to store the
 * key in it, because after the call, the entry will be persisted in the har file. In this case, the key parameter either
 * comes from a call to {@link IMock.setMockHarKey}, or from {@link IMock.defaultMockHarKey | defaultMockHarKey}.
 *
 * In order to compute the {@link IMock.defaultMockHarKey | defaultMockHarKey} property, the har key manager
 * is called with an entry that includes the request but not the response (and with an undefined key parameter).
 *
 * In all cases, the har key manager is expected to return the key of the entry. If an array is returned (which can
 * be nested), it is flattened with null items removed, and joined with forward slashes to produce a string.
 *
 * The default har key manager is expected to work fine for most use cases, especially when working with a har file recorded
 * with kassette. With the default har key manager, if a key is set with {@link IMock.setMockHarKey}, it is stored in the
 * {@link HarFormatEntry._kassetteMockKey | _kassetteMockKey} field. Otherwise, the default key is the concatenation of the request
 * method and url, with a separating forward slash. It can be useful to replace the default har key manager with a custom one especially
 * when working with har files that are produced by other applications than kassette, if the default key is not convenient.
 *
 * @example
 *
 * Here is the default har key manager:
 * ```ts
 * export const defaultHarKeyManager: HarKeyManager = (entry: HarFormatEntry, key?: string) => {
 *   const defaultKey = joinPath(entry._kassetteMockKey ?? [entry.request?.method, entry.request?.url]);
 *   if (key && key !== defaultKey) {
 *     entry._kassetteMockKey = key;
 *     return key;
 *   }
 *   return defaultKey;
 * };
 * ```
 *
