fix(cache): log cache errors as trace

[JamieMagee]

Changes:

Log errors caught by the cache decorator as trace.

This matches what's done further up the stack in datasource/index.ts: [1], [2]. The error will eventually bubble up to logError, where selective details from it are logged at the debug level, instead of the entire error:

renovate/lib/datasource/index.ts

Lines 36 to 50 in d3bce1b

	function logError(datasource, lookupName, err): void {
	const { statusCode, code: errCode, url } = err;
	if (statusCode === 404) {
	logger.debug({ datasource, lookupName, url }, 'Datasource 404');
	} else if (statusCode === 401 || statusCode === 403) {
	logger.debug({ datasource, lookupName, url }, 'Datasource unauthorized');
	} else if (errCode) {
	logger.debug(
	{ datasource, lookupName, url, errCode },
	'Datasource connection error'
	);
	} else {
	logger.debug({ datasource, lookupName, err }, 'Datasource unknown error');
	}
	}

While I could split this into 3 different try/catch blocks (for the cache get, the method call, and the cache set) I think these parts are less likely to throw an error.
