     * * `.`    multiplication or composition (as an infix operator). For
     *          examples, `GBy.d` or `k{watt}.h`.
     * The grammar for a unit is as follows:
     *     Expression = Component { "." Component } { "/" Component } ;
     *     Component = ( [ PREFIX ] UNIT | "%" ) [ Annotation ]
     *               | Annotation

     *     Annotation = "{" NAME "}" ;
     * Notes:
     * * `Annotation` is just a comment if it follows a `UNIT`. If the annotation
     *    is used alone, then the unit is equivalent to `1`. For examples,
     *    `{request}/s == 1/s`, `By{transmitted}/s == By/s`.
     * * `NAME` is a sequence of non-blank printable ASCII characters not
     *    containing `{` or `}`.
     * * `1` represents a unitary [dimensionless
     *    unit](https://en.wikipedia.org/wiki/Dimensionless_quantity) of 1, such
     *    as in `1/s`. It is typically used when none of the basic units are
     *    appropriate. For example, "new users per day" can be represented as
     *    `1/d` or `{new-users}/d` (and a metric value `5` would mean "5 new
     *    users). Alternatively, "thousands of page views per day" would be
     *    represented as `1000/d` or `k1/d` or `k{page_views}/d` (and a metric
     *    value of `5.3` would mean "5300 page views per day").
     * * `%` represents dimensionless value of 1/100, and annotates values giving
     *    a percentage (so the metric values are typically in the range of 0..100,
     *    and a metric value `3` means "3 percent").
     * * `10^2.%` indicates a metric contains a ratio, typically in the range
     *    0..1, that will be multiplied by 100 and displayed as a percentage
     *    (so a metric value `0.03` means "3 percent").

     * **Grammar**
     * The grammar also includes these connectors:
     * * `/`    division or ratio (as an infix operator). For examples,
     *          `kBy/{email}` or `MiBy/10ms` (although you should almost never
     *          have `/s` in a metric `unit`; rates should always be computed at
     *          query time from the underlying cumulative or delta value).
     * * `.`    multiplication or composition (as an infix operator). For
     *          examples, `GBy.d` or `k{watt}.h`.
     * The grammar for a unit is as follows:
     *     Expression = Component { "." Component } { "/" Component } ;
     *     Component = ( [ PREFIX ] UNIT | "%" ) [ Annotation ]
     *               | Annotation
     *               | "1"
     *               ;
     *     Annotation = "{" NAME "}" ;
     * Notes:
     * * `Annotation` is just a comment if it follows a `UNIT`. If the annotation
     *    is used alone, then the unit is equivalent to `1`. For examples,
     *    `{request}/s == 1/s`, `By{transmitted}/s == By/s`.
     * * `NAME` is a sequence of non-blank printable ASCII characters not
     *    containing `{` or `}`.
     * * `1` represents a unitary [dimensionless
     *    unit](https://en.wikipedia.org/wiki/Dimensionless_quantity) of 1, such
     *    as in `1/s`. It is typically used when none of the basic units are
     *    appropriate. For example, "new users per day" can be represented as
     *    `1/d` or `{new-users}/d` (and a metric value `5` would mean "5 new
     *    users). Alternatively, "thousands of page views per day" would be
     *    represented as `1000/d` or `k1/d` or `k{page_views}/d` (and a metric
     *    value of `5.3` would mean "5300 page views per day").
     * * `%` represents dimensionless value of 1/100, and annotates values giving
     *    a percentage (so the metric values are typically in the range of 0..100,
     *    and a metric value `3` means "3 percent").
     * * `10^2.%` indicates a metric contains a ratio, typically in the range
     *    0..1, that will be multiplied by 100 and displayed as a percentage
     *    (so a metric value `0.03` means "3 percent").

     * The units in which the metric value is reported. It is only applicable
     * if the `value_type` is `INT64`, `DOUBLE`, or `DISTRIBUTION`. The `unit`
     * defines the representation of the stored metric values.
     * Different systems might scale the values to be more easily displayed (so a
     * value of `0.02kBy` _might_ be displayed as `20By`, and a value of
     * `3523kBy` _might_ be displayed as `3.5MBy`). However, if the `unit` is
     * `kBy`, then the value of the metric is always in thousands of bytes, no
     * matter how it might be displayed.
     * If you want a custom metric to record the exact number of CPU-seconds used
     * by a job, you can create an `INT64 CUMULATIVE` metric whose `unit` is
     * `s{CPU}` (or equivalently `1s{CPU}` or just `s`). If the job uses 12,005
     * CPU-seconds, then the value is written as `12005`.
     * Alternatively, if you want a custom metric to record data in a more
     * granular way, you can create a `DOUBLE CUMULATIVE` metric whose `unit` is
     * `ks{CPU}`, and then write the value `12.005` (which is `12005/1000`),
     * or use `Kis{CPU}` and write `11.723` (which is `12005/1024`).
