Description

We have several places in LocalIgfsSecondaryFileSystem where IOException is thrown. This is not correct, because:
1) Exception must be specific. E.g. "path-not-found-exception".
2) It doesn't make sense to throw IOException and cast it to IgfsException immediately.

Also we should not throw IgniteException. Proper IgfsException must be thrown.

Let's review all these places and replace IOException with proper IgfsException inheritor.

Successful implementation should not introduce any new test failures.
