Add logger middleware template variables: ${time_unix_milli} and ${time_unix_micro} (#2206)

Browse Source 
This patch introduces two template variables `${time_unix_milli}` and
`${time_unix_micro}` into the logger middleware.
Currently, there is no way to interpolate that UNIX milli and micro
seconds timestamp in a log entry, and go 1.17 or later runtime supports
the utility functions `time#UnixMilli()` and `time#UnixMicro()`
so this patch adds them as well.
