[RFE]: don't allow illegal characters in plan names

[Udi Kalifon]

When creating a new plan, characters which are illegal in hostnames should also be illegal in the plan name. This is important because the nodes' host names are a concatenation of the plan name + role + index, by default.

For example, underscores are not allowed in host names. If I create a new plan and call it "plan_1" I will get nodes with names like plan_1-controller-X, plan_1-compute-X etc... This can cause some deployments to fail, for example I know that deployments with predictable IPs (from pools) fail when you do this.

    Disallow underscores in plan names

    Plan names are included in the node hostnames created during
    deployment. However underscores are not actually allowed in hostnames,
    and having them there can cause issues down the line.

    Validate the plan name before running

    By default the plan name is used on the creation of the node name
    in the form of plan_name + role + index

    Forcing the plan name to be only letters and numbers removes the
    possibility of a failed deploy due to an invalid node name

    I've included a pattern validator to verify that those names are valid
    and a constant for node and plan name validation
