It was introduced in 69e1e6ca to help node determine faulty shards.
However, the situation is possible in a real-life scenario:
1. Object O is evacuated from shard A to B.
2. Shard A is unmounted because of lower-level errors.
3. We now have object in meta on A and in blobstor on B. Technically we
have it in meta on shard B too, but we still got the error if B goes
to a degraded mode.

Supposedly, this was added to allow creating 2 different shards without
subtest. Now we use t.TempDir() everywhere, so this should not be a
problem.

newCustomShard() has many parameters but only the first is obligatory.
`enableWriteCache` is left as-is, because it directly affects the
functionality.

This was set in #348 to speed up tests.
It seems 100ms doesn't increase overall test time,
but it reduces the amount of logs by 100x factor.

In some places we have debug=false, in others debug=true.
Let's be consistent.

Protect test metric store fields with a mutex. Probably, not every field
should be protected, but better safe than sorry.

Some of our pilorama tests fail on CI.
The reasons are not obvious, but one possible improvement
is using `WithNoSync` option for these. It should have much effect,
because we are writing on the tmpfs, but doesn't hurt anyway.
If I replace `t.TempDir()` with a local directory, test execution time
goes down from 5s (sync) to 0.4s (nosync), which is the same time as
with `t.TempDir()`. Maybe we have some strange CI configuration.
