Add a new entity provider `BitbucketCloudEntityProvider`
as a new plugin `@backstage/plugin-catalog-backend-module-bitbucket-cloud`.
The new plugin utilizes `@backstage/plugin-bitbucket-cloud-common`
and it fully independent of `@backstage/plugin-catalog-backend-module-bitbucket`
which provides a catalog processors supporting Bitbucket Cloud and Bitbucket Server.
