This commit modifies the DSL for custom layer configuration in the
Gradle plugin to avoid duplication of terms that could be confusing.

`compileJava.dependsOn(processResources)` is not enough to ensure the
correct behavior. Using `dependsOn` only affects the execution order
(`processResources` before `compileJava`) but not the up-to-date check
of `compileJava`. After modifying
`META-INF/additional-spring-configuration-metadata.json`, the
`processResouces` task will considered out-of-date and will be
re-executed, but after that `compileJava` will still be considered
up-to-date which causes the changes not to be merged into
`META-INF/spring-configuration-metadata.json`

With this change the up-do-date check of `compileJava` is affected,
too. Therefore, it will correctly re-execute the
configuration-processor when
`META-INF/additional-spring-configuration-metadata.json` was changed.

This commit adds support for setting the image name and builder
parameters of the Maven spring-boot:build-image goal using command-line
properties as an alternative to plugin configuration in pom.xml. Per
Maven conventions, a value in pom.xml configuration will override a
command-line property when both are provided.

The upgrade to the Couchbase SDK v3 changed how errors are reported
when the cluster is not available. This commit updates the check to
look for the new exception in the hope a more solid check can be found
shortly.

This commit expands the `spring.couchbase.env.timeouts` configuration

This commit upgrades to the Couchbase SDK v3 which brings the following
breaking changes:

* Bootstrap hosts have been replaced by a connection string and the
authentication is now mandatory.
* A `Bucket` is no longer auto-configured. The
`spring.couchbase.bucket.*` properties have been removed
* `ClusterInfo` no longer exists and has been replaced by a dedicated
API on `Cluster`.
* `CouchbaseEnvironment` no longer exist in favour of
`ClusterEnvironment`, the customizer has been renamed accordingly.
* The bootstrap-related properties have been removed. Users requiring
custom ports should supply the seed nodes and initialize a Cluster
themselves.
* The endpoints-related configuration has been consolidated in a
single IO configuration.

The Spring Data Couchbase provides an integration with the new SDK. This
leads to the following changes:

* A convenient `CouchbaseClientFactory` is auto-configured.
* Repositories are configured against a bucket and a scope. Those can
be set via configuration in `spring.data.couchbase.*`.
* The default consistency property has been removed in favour of a more
flexible annotation on the repository query methods instead. You can now
specify different query consistency on a per method basis.
* The `CacheManager` implementation is provided, as do other stores for
consistency so a dependency on `couchbase-spring-cache` is no longer
required.

This commit configures Spring Data Couchbase explicitly rather than
relying on the abstract configuration class. This has the advantage of
simplifying the auto-configuration and let it us proxy-free
configuration classes.

Spring Boot no longer uses or interacts with CouchbaseConfigurer. Users
relying on that to teach Spring Boot which components to use should
rely on `@Primary` flag instead in case of multiple beans of the same
type.

`CouchbaseConfiguration` is no longer public as extending from it is
no longer necessary. If the `CouchbaseEnvironment` has to be
customized, a `CouchbaseEnvironmentBuilderCustomizer` bean can be
registered to tune the auto-configured environment.

Previously, any HTTP request to an endpoint that included a principal
would bypass the cache. This prevented authenticated requests from
making use of the cache and its configurable time-to-live.

This commit updates the caching operation invoker to include the
principal, if any, in its cache key. As a result, requests that
include a principal will make use of the cache, potentially returning
the result of a previous invocation of the same endpoint by the same
principal.
