This should reduce amount of code that should be recompiled on
Exception.h changes (and everything else that had been included there).
This will actually not help a lot, because it is also included into
PODArray.h and ThreadPool.h at least... Sigh.

Reading from S3 has retries on almost any exception, except for
CANNOT_ALLOCATE_MEMORY, but the problem is that this exception may not
be even delivered to ReadBufferFromS3::processException(), due to
std::istream will hide it (see [1]).
[1]: 1834e42289/libcxx/include/istream (L1059)
So let's pass throught them to see at least some information instead of
just:
Message: Cannot read from istream at offset 0
And here as an example of exception:
