This change is only moving packages and updating import paths. Goal: expose `internal/pkg/provision` as `pkg/provision` to enable other projects to import Talos provisioning library. As cluster checks are almost always required as part of provisioning process, package `internal/pkg/cluster` was also made public as `pkg/cluster`. Other changes were direct dependencies discovered by `importvet` which were updated. Public packages (useful, general purpose packages with stable API): * `internal/pkg/conditions` -> `pkg/conditions` * `internal/pkg/tail` -> `pkg/tail` Private packages (used only on provisioning library internally): * `internal/pkg/inmemhttp` -> `pkg/provision/internal/inmemhttp` * `internal/pkg/kernel/vmlinuz` -> `pkg/provision/internal/vmlinuz` * `internal/pkg/cniutils` -> `pkg/provision/internal/cniutils` Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
