NuGet: OpenTelemetry.Sampler.AWS v0.1.0-alpha.16

• Fixed a bug where a transient failure fetching sampling rules from the
  X-Ray daemon/collector (e.g. a network error or an unparsable response)
  would wipe out the previously cached rules instead of being ignored. This
  could cause the sampler to temporarily fall back to a low-fidelity default
  sampling strategy, discard any sampling targets already applied, and
  recreate rule appliers from scratch on the next successful poll.
  (#5424)

• Fixed a bug where the remote sampler's target poller could busy-loop
  when a rule applier had never received a sampling target and the clock's
  "now" landed exactly on that applier's initial snapshot time.
  (#5424)

• The globs of sampling rules (such as a URLPath of /health*) must now match
  the whole attribute value instead of matching wherever they occur in the value.
  (#5455)

• Fixed the rule and target pollers stopping indefinitely after a response they
  could not apply. Invalid rules and targets are now skipped and logged, only the
  first of several rules with the same RuleName is used, the Interval of a target
  is limited to 5 minutes, and the next poll is scheduled even if a poll fails.
  (#5455)

• Requests to the sampling endpoint now time out after 10 seconds.
  (#5455)

• Updated OpenTelemetry core component version(s) to 1.20.0.
  (#5541)
