We will hardfork NOMAD and run v1.0.0 on new databases that will not support the old search index (and therefore most of the old flask API).

• remove v0 search and unify the search module once again
• remove the old metainfo search extension that drove the v0 index
• remove all of the old v0 API and its tests
• remove obsolete commands from client CLI (mirror, statistics?)
• migrate the integrationtests to v1 API
• migrate upload CLI to v1 API
• migrate local CLI to v1 API
• migrate aflow update to v1 API
• migrate uploads CLI to v1 search
• migrate Optimade API
• migrate dcat API
• migrate client.py to v1 API
• move lots of tiny API functions to v1 (done in #607 (closed))
• temporarily add the old edit API to v1 (done in #607 (closed))
• migrate all examples to requests and v1 API
• remove .dft (and other domains)
• remove nomad.cli.client.legacy._create_client
• "test" the GUI after refactors
• test the deployment

This depends on #588 and #607 (closed).
