[tor-project] metrics-lib 2.18.0 released

[Iain R. Learmonth]

Hi,

I have released metrics-lib 2.18.0. This release is particularly exciting as it
contains contributions from 3 seperate developers, this codebase is getting
some attention!

metrics-lib, which also goes by the name DescripTor, is a Java API that
fetches Tor descriptors from a variety of sources like cached
descriptors and directory authorities/mirrors. The DescripTor API is
useful to support statistical analysis of the Tor network data and for
building services and applications.

This release is the sum of over 9 years of development, with the latest
changes:

 * Medium changes
   - Expose overload-ratelimits and overload-fd-exhausted
     fields in ExtraInfoDescriptor. (hiro)
   - OnionPerfAnalysisConverter discards circuits marked as
     filtered. (acute)
   - Adds BridgestrapStats to parse metrics from bridgestrap. (irl)
