This updates upgrade tests to run two flows with 3+1 clusters: 1. 0.3 -> current (testing upgrade with partition wiping) 2. 0.4-alpha.7 -> current (testing upgrade without partition wiping, boot-a/boot-b) And small upgrade with preserve enabled for single-node cluster. Provision tests are now split into two parallel tracks in Drone. Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
