ILM UI does not handle max docs and max size properly

[bmcconaghy]

I have a policy that is showing up in Kibana as
"hot": { "min_age": "0ms", "actions": { "rollover": { "max_age": "30d", "max_docs": 1000000 } }

but it is defined in ES as this:

The issue here is twofold: the new default values are kicking in for defined policies (hence the 30 days showing in Kibana), and Kibana only allows for choosing max_size or max_docs, and so last one in wins in the code. Additionally, Kibana does not support mb as a size unit for max size.
