When importing clusters from a file, grow the used buffer to the correct size of the next cluster, so that it does not panic when unmarshaling it.
Handle panics on the storage's save & load, so that it will never crash the discovery service when it fails.
Additionally:
- fix the slice growing logic when exporting clusters so that we avoid over-growing the slices for the affiliates and the endpoints.
- modify the storage tests to use the real state instead of a mock, replace the assertions to ignore the order accordingly.

On a best-effort basis, store the state on the disk periodically and on shutdown & restore it from the disk on startup.
Additionally, bump Go version, deps & rekres.
