Expose max auto resizes metric

Currently, only the number of auto resizes is exposed as a metric.
When this value reaches 0 it is no longer possible to
expand the cache.

However, it is not possible to know the maximum number of auto-resizes
that the cache could go through.

Expose the maximum number of auto-resizes as a metric, so that can be
used together with the remaining auto-resizes to evaluate the overall
utilization of the cache.

  • Install cache-chronicalmap module

Install the chronicle-map module into the $GERRIT_SITE/lib directory.

Add the cache-chroniclemap module to $GERRIT_SITE/etc/gerrit.config as follows:

[gerrit]
  installModule = com.googlesource.gerrit.modules.cache.chroniclemap.ChronicleMapCacheModule

For further information and supported options, refer to config documentation.
