Add readonly type to stores

Description

Readonly stores are stores that cannot be changed via the rest command line. Only two ways of writing into the store:

1) via load (via boostrap mechanism)
2) via a stream using configuration

Both of which means write access to the store. We should also consider things like only owners are allowed to make modifications to the store. We only have 1 group right now.
