Support S3Path.resolve(Path) for non-S3Path arguments

[ennoruijters]

This is a partial resubmission of Upplication/Amazon-S3-FileSystem-NIO2#104, which was made by my colleague @sbeimin.

Task Description

S3Path.resolve(Path) currently assumes that its argument is always another S3Path, and throws a ClassCastException if it is not (except for absolute paths, for which you do get a neat error message).

This is inconvenient for us, as we often store relative paths internally using the result of java.nio.file.Paths.get("example/file"). I propose to allow other Path types as arguments for relative paths.

Tasks

The following tasks will need to be carried out:

• Allow relative non-S3Path paths as arguments to S3Path.resolve().
• Include unit tests.
