Update `WebEndpointDiscoverer` and related classes to that multiple
`PathMapper` beans can be registered. Mappers are now tried in order
until one returns a non-null value.

Previously, Couchbase's health was determined by retrieving the bucket info
from the cluster info. This retrieval could take over one minute in some
cases even when Couchbase is health. This latency is too large for a health
check.
The Couchbase team have recommended the of a Cluster#diagnostics instead.
This provides a much lower latency view of the cluster's health. This
commit updates CouchbaseHealthIndicator to use Cluster#diagnostics while
retaining support, in a deprecated form, for the old info-based mechanism
should anyone want to opt back into that in 2.0.x.

Update `ExposeExcludePropertyEndpointFilter` so that mixed case
endpoint IDs are supported. Prior to this commit it was not easy for
an endpoint to be missed by the filter due to the formatting of the
property value.
See gh-14773
Update the endpoint time-to-live binding logic so that mixed case
endpoint IDs are supported. Prior to this commit an
`InvalidConfigurationPropertyNameException` would be thrown when using
a camel case endpoint ID.
See gh-14773
Add an `EndpointID` class to enforce the naming rules that we support
for actuator endpoints. We now ensure that all endpoint names contain
only letters and numbers and must begin with a lower-case letter.
Existing public classes and interfaces have been changes so that String
based `endpointId` methods are deprecated and strongly typed versions
are preferred instead. A few public classes that we're not expecting
to be used directly have been changed without deprecated methods being
introduced.

Update `MetricsEndpoint` so that only the first matching meter is used
when calculating the sum of of statistics.
Prior this this commit the endpoint would consider all Meters. This
caused incorrect statistics when multiple back-end systems were being
used since the registries contained in the `CompositeMeterRegistry`
would be iterated, and the same effective metric would be counted more
than once.

Previously, the API required to create HttpTrace instances was
package-private. This made it difficult to implement an
HttpTraceRepository that persists the HttpTrace instances
rather than holding them in memory as it inhibited recreation of the
instances when they read from the persistent store.
This commit adds public constructors to HttpTrace and related classes
to enable recreation of an HttpTrace. The package-private methods for
mutating properties have not been made public to ensure that the
public API remains immutable.
Closes gh-14726
Previously, if the call to connection.start() hung, JmsHealthIndicator
would also hang and then never respond.
This commit introduces the use of an additional thread that waits for
up to 5 seconds for the connection to start. If the call to start
does not complete within that time, the connection is closed. The
call to close causes the call to start to throw an exception, thereby
stopping the hang and allowing the indicator to report that the
broker is down.
Closes gh-10809
Rework Prometheus push gateway support so that the central class can
be used outside of auto-configuration. The shutdown flags have also
been replaced with a single "shutdown-operation" property since it's
unlikely that both "push" and "delete" will be required.
It's also possible now to supply a `TaskScheduler` to the manager.
See gh-14353
