Calvin Leung Huang 3b8b68097d Lazy-load plugin mounts (#3255)
* Lazy load plugins to avoid setup-unwrap cycle

* Remove commented blocks

* Refactor NewTestCluster, use single core cluster on basic plugin tests

* Set c.pluginDirectory in TestAddTestPlugin for setupPluginCatalog to work properly

* Add special path to mock plugin

* Move ensureCoresSealed to vault/testing.go

* Use same method for EnsureCoresSealed and Cleanup

* Bump ensureCoresSealed timeout to 60s

* Correctly handle nil opts on NewTestCluster

* Add metadata flag to APIClientMeta, use meta-enabled plugin when mounting to bootstrap

* Check metadata flag directly on the plugin process

* Plumb isMetadataMode down to PluginRunner

* Add NOOP shims when running in metadata mode

* Remove unused flag from the APIMetadata object

* Remove setupSecretPlugins and setupCredentialPlugins functions

* Move when we setup rollback manager to after the plugins are initialized

* Fix tests

* Fix merge issue

* start rollback manager after the credential setup

* Add guards against running certain client and server functions while in metadata mode

* Call initialize once a plugin is loaded on the fly

* Add more tests, update basic secret/auth plugin tests to trigger lazy loading

* Skip mount if plugin removed from catalog

* Fixup

* Remove commented line on LookupPlugin

* Fail on mount operation if plugin is re-added to catalog and mount is on existing path

* Check type and special paths on startBackend

* Fix merge conflicts

* Refactor PluginRunner run methods to use runCommon, fix TestSystemBackend_Plugin_auth
