this patch adds support for tenants. This touches mostly pageserver. Directory layout on disk is changed to contain new layer of indirection. Now path to particular repository has the following structure: <pageserver workdir>/tenants/<tenant id>. Tenant id has the same format as timeline id. Tenant id is included in pageserver commands when needed. Also new commands are available in pageserver: tenant_list, tenant_create. This is also reflected CLI. During init default tenant is created and it's id is saved in CLI config, so following commands can use it without extra options. Tenant id is also included in compute postgres configuration, so it can be passed via ServerInfo to safekeeper and in connection string to pageserver. For more info see docs/multitenancy.md.
