webadmin: Add IDs to main events view table

The events table used default ids. To allow
testing of the cluster upgrade, where the events
table shows the progress of the upgrade, it is
more convenient to use specific ids.

This patch adds ViewIdHandler to MainEventView that
generates ids with MainEventView_ prefix.
