Tempest: Create custom flavor for running tempest test in VM

tempest requires to have an alternative flavor and the m1.small flavor
by default is very big in terms of RAM and disk for a test VM.
Adding the possibility to set a smaller custom flavor gives the
possibility to run tempests test for onenode in a VM without having
memory or disk allocation problems with libvirt.
