  Add profiles directly to the application environment for tests

Closes gh-19556

Prior to this commit, active profiles were being added to the Spring Boot
application environment by setting the `spring.profiles.active` property.
This could result in profiles getting parsed differently than other uses of `@ActiveProfiles`.
Setting the profiles directly in the `Environment` prevents this parsing.

Prior to this commit, the `ErrorController` would override the original
error response status if the error map cannot be written due to content
negotiation with the HTTP client. In that case, the error handling
infrastructure returns a `406 Not Acceptable` response.

This commit improves the `ErrorController` so that
`HttpMediaTypeNotAcceptableException` instances thrown by that
controller are not returned as is but instead we write the error
response with an empty body and the original HTTP error status.

Prior to this commit, there was no distinction between explicitly setting
forward headers strategy to a value of NONE and not setting it at all.
This meant that in a cloud environment, a cloud provider was always checked
to see if it was active and using forward headers and there was no way to
prevent that.

This commit changes the default value of the property to null so that there
is a way to determine if the property was explicitly set to NONE.

Prior to this commit, the Couchbase auto-configuration would use the
bucket credentials when RBAC is configured. This commit ensures that
RBAC is used in that case.

This commit also adds new configuration properties to customize the
bootstrap ports for Couchbase:

* `spring.couchbase.env.bootstrap.http-direct-port`
* `spring.couchbase.env.bootstrap.http-ssl-port`
