Update the open_source_licenses file to reflect the fact that the
org.json library is no longer used.

Closes gh-7703

Update all `EmbeddedServletContainer` implementations to ensure that
the `start()` method can be called multiple times, with the second call
being ignored.

Fixes gh-8036

Update `Log4J2LoggingSystem` and `LogbackLoggingSystem` to ensure
that filters are removed when the `cleanUp` method is called. Prior
to this commit application failures would not remove the filter and
no log messages would appear.

The `LoggingApplicationListener` has also been updated since it
previously failed to handle `ApplicationFailureEvents`.

Finally `EventPublishingRunListener` and `DelegatingApplicationListener`
have been updated to deal with `null` parameters and to cope with
listener errors.

Fixes gh-7758

This reverts commit 70cd5c42.

See gh-8083

In version 2.3.6 and earlier, an attempt to create a Bucket or a
ClusterInfo would fail fast with a ConnectException in the cause of
the Couchbase server was done. In 2.3.7 this remains true for a
Bucket but is no longer the case for ClusterInfo. The latter now
retries for 75 seconds by default and when it eventually fails a
ConnectException is no longer part of the cause chain.

This commit makes the auto-configured ClusterInfo depend on the
auto-configured Bucket. This means that the Bucket is always created
before the ClusterInfo, thereby ensuring that things fail gracefully
with useful diagnostics when the server is unavailable.

Previously, AbstractEmbeddedServletContainerFactory detected an
exploded war by looking for `/WEB-INF/` in the path of its code
source's location. This failed on Windows due to the use of `\` rather
than `/` separators.

This commit updates AbstractEmbeddedServletContainerFactory to
uses the OS's separator rather than hardcoding `/`.
