Problems of Azure related to ray bug

[Michaelvll]

The Azure is now usable, though there are two problems related to ray that needs to be further investigated:

• ray up for Azure will ignore the cluster_name, reusing the existing instance. [Fixed in Fix Azure restarting existing instance with different cluster_name #111 ]
• After ray up commend is finished, it sometimes takes a while for the cluster to be available for ray, especially for Azure, which will cause the ray exec and ray get_head-node-ip in our code to fail.

local ray version: 1.9.0
remote ray version: 1.7.0
