4ef9baf5bd Only invoke a given cached partial once
Note that this is backed by a LRU cache (which we soon shall see more usage of), so if you're a heavy user of cached partials it may be evicted and
refreshed if needed. But in most cases every partial is only invoked once.

This commit also adds a timeout (the global `timeout` config option) to make infinite recursion in partials
easier to reason about.

6a5acd753a metrics: Fix divide by zero error
Under certain conditions, `howSimilarString` could reach a divide-by-
zero situation which causes bogus values to print in the cache potential
column of the template hints output.  This situation essentially causes
a `int(math.NaN())` value to be returned and hilarity ensues thereafter.

51f08b0b6a Revise the use of htime.Since/htime.Now
We cannot (also, it doesn't add any value)  use that when the `clock` is set,

* To measure time (before that global is set)
* To compare file timestamps re cache eviction

d16228334d metrics: Add cached count tracking
Track cached partial executions and display more useful info when
showing the hints output. Also group cache hints and counters together
to the right of the timing measurements.

Sample output:

tpl: Allow the partial template func to return any type
This commit adds support for return values in partials.

This means that you can now do this and similar:

    {{ $v := add . 42 }}
    {{ return $v }}

Partials without a `return` statement will be rendered as before.

This works for both `partial` and `partialCached`.

5800a20a25 metrics: Detect partialCached candidates
This commit adds a "cache potential" column when running `hugo --templateMetrics --templateMetricsHints`.

This is only calculated when `--templateMetricsHints` is set, as these calculations has an negative effect on the other timings.

This gives a value for partials only, and is a number between 0-100 that indicates if `partial` can be replaced with `partialCached`.

100 means that all execution of the same partial resulted in the same output.

You should do  some manual research before going "all cache".
