Limit number of builds to display in status-bubble hover over message in case of lot of retried builds. Sometimes because of retries, one patch can be retried a lot of times. e.g.: https://ews-build.webkit.org/#/builders/29/builds/5682 (Bug https://bugs.webkit.org/show_bug.cgi?id=209008) In such cases status-bubble generation might become slow if the status-bubble shows history from all builds (e.g.: while one of the build is in-progress, or last build was skipped because of patch being obsolete/bug-closing). The slowness is because the hover-over message will become huge, and the calculation itself might take a while because of large number of builds.
