[library] Fuel master node upgrade fails on master node with 1GB RAM

[Sergii Golovatiuk]

When Master node has 1-1.5 GB of RAM, lrzip cannot unpack upgrade archive and fails with the following error

[root@nailgun upgrade]# Failed to allocate 1121264436 bytes for decompression
Failed to allocate 1121264436 bytes for decompression
Failed to decompress in ucompthread

The documentation should be updated and declares that master node must have at least 2GB of RAM. Alternatively the operator can unpack tar somewhere else and copy 'upgrade' tarball to master node.

Actually, the documentation DOES say that the Fuel Master must have at least 2GB of RAM: http://docs.mirantis.com/openstack/fuel/master/planning-guide.html#master-node-hardware-recommendations. Still, I will add a note to upgrade.
