Add constrained labels and Constrained variant for all MetricVecs (#1151) 
* Introduce MetricVecOpts and add constraints to VariableLabels

MetricVecOpts exposes options specific to MetricVec initialisation. The
first option exposed by MetricVecOpts are constraints on VariableLabels,
allowing restrictions on the possible values a label can take, to
prevent cardinality explosion when the label value comes from a
non-trusted source (as a user input or HTTP header).
