* feat: timing statistics for getReleases
Adds collection and reporting of timing statistics for
`datasource.getReleases()` calls. Each call records the datasource, registryUrl,
packageName, and duration. The intent is to visibility into where
renovate is retrieving release information and how long that might take.
The report consists of a nested data-structure that provides increasing
detail as we descend datasource, registryUrl, and packageName.
The full report is logged at trace level
`getReleases statistics with packages`.
A summary report including only datasources and registryUrls is logged
at debug level `getReleases statistics summary`.
* add GetReleasesSpanProcessor
