sneak f0eb4f0650 Send fx's own events through the service's logger (closes #183)
check / check (push) Successful in 3m46s
Details 
fx printed its dependency graph and its start and stop hooks through
its console logger on standard error. fx.WithLogger now hands those
events to the service's logger: building the graph at DEBUG, the hooks,
the start and the stopping signal at INFO, failures at ERROR. The fx
logger's constructor takes the configuration, so the level DEBUG=true
sets is in force before fx replays the events it held back. fx's
SlogLogger takes one level for everything that is not a failure, so
FxLogger in internal/logger holds one at each level. fx moves from
v1.20.1, which has no SlogLogger, to v1.24.0. The README names the Go
runtime as a writer whose output cannot be redirected.
