   * Optional. This allows you to specify the "context" for a Trial; a context
   * is a slice (a subspace) of the search space. Typical uses for contexts: 1)
   * You are using Vizier to tune a server for best performance, but there's a
   * strong weekly cycle. The context specifies the day-of-week. This allows
   * Tuesday to generalize from Wednesday without assuming that everything is
   * identical. 2) Imagine you're optimizing some medical treatment for people.
   * As they walk in the door, you know certain facts about them (e.g. sex,
   * weight, height, blood-pressure). Put that information in the context, and
   * Vizier will adapt its suggestions to the patient. 3) You want to do a fair
   * A/B test efficiently. Specify the "A" and "B" conditions as contexts, and
   * Vizier will generalize between "A" and "B" conditions. If they are similar,
   * this will allow Vizier to converge to the optimum faster than if "A" and
   * "B" were separate Studies. NOTE: You can also enter contexts as REQUESTED
   * Trials, e.g. via the CreateTrial() RPC; that's the asynchronous option
   * where you don't need a close association between contexts and suggestions.
   * NOTE: All the Parameters you set in a context MUST be defined in the Study.
   * NOTE: You must supply 0 or $suggestion_count contexts. If you don't supply
   * any contexts, Vizier will make suggestions from the full search space
   * specified in the StudySpec; if you supply a full set of context, each
   * suggestion will match the corresponding context. NOTE: A Context with no
   * features set matches anything, and allows suggestions from the full search
   * space. NOTE: Contexts MUST lie within the search space specified in the
   * StudySpec. It's an error if they don't. NOTE: Contexts preferentially match
   * ACTIVE then REQUESTED trials before new suggestions are generated. NOTE:
   * Generation of suggestions involves a match between a Context and
   * (optionally) a REQUESTED trial; if that match is not fully specified, a
   * suggestion will be geneated in the merged subspace.
