Previously, alternator server was not directly sharded - and instead kept a helper http server control class, which stored sharded http server inside. That design is confusing and makes it hard to expand alternator server with new sharded attributes, so from now on the alternator server is itself sharded<>. Tests: alternator-test(local, smp==1&smp==4) Fixes #5913 Message-Id: <b50e0e29610c0dfea61f3a1571f8ca3640356782.1582788575.git.sarna@scylladb.com>
