No documentation on metaspace size

[pwonson]

Describe the bug Many Rundeck users have issues where the default metaspace size is too small. The following page should have guidelines on fixing the related error when running out of space

java.lang.OutOfMemoryError: Metaspace

The only mention of it is here but there is no mention of when it would need to be increased or why. Support tells them to increase when they get the error.
