Previously, the health auto-configuration `AutoconfigureOrder` entry for
couchbase was referring to the standard couchbase auto-configuration that
is not responsible to configure the `CouchbaseOperations` bean. Yet, the
health indicator implementation was relying on the presence of such a
bean.

This commit fixes the `AutoconfigureOrder` entry so that it refers to
`CouchbaseDataAutoConfiguration` now.

Previously, if a user specifies a path to a schema or data DDL that does
not exist, the application will start up fine and the missing DDL would
not be reported.

This commit validates that user-defined resources actually exist and
throw a new `ResourceNotFoundException` if they don't.

This commit uses standard files for libraries managed by the repackage
goal of the Maven plugin. Previously, only the name of the file was used
which could lead to duplicate libraries if the name of the target file
deviates from the default. This typically happens when the
`build.finalName` property is specified on a dependent module.

Note that the `maven-war-plugin` has an additional mechanism to customize
the file name structure of dependencies. This feature isn't supported by
the repackage goal so an explicit mention has been added in the
documentation.

Closes gh-7389

Previously, if `spring.couchbase.bootstrap-hosts` was specified in YAML
or with the `[Idx]` notation, the auto-configuration would not kick in.

This is due to a limitation of `@ConditionalOnProperty` on a property of
type Collection. This commit workarounds this limitation for now with a
dedicated condition.

Closes gh-7508

This commit promotes the plugin dependency management for the
`maven-enforcer-plugin` and `maven-invoker-plugin` to the root. That way
these can be used in samples as well rather than having a separate copy.
