Fixing bug: Not able to ssh into VM with password

When user create VM with user name and password, the LinuxProvisioningConfiguration node should contain
the child node ‘disableSshPasswordAuthentication’ with value false. CLI already set this member variable to Boolean false, but hydra SDK is ignoring this. Looks like it takes more time to get this fixed in Hydra SDK so doing a temporary fix in CLI tool by passing false as string.
