Create additional Couchbase backends during install

[yurem]

We need to create 5 buckets per this config to split data between buckets and allow to specify their type for optional performance.

Here is full list of buckets: gluu (default), gluu_user (for ou=people/ou=group), gluu_session (ou=sessions), gluu_statistic(ou=metric), gluu_site(o=site).

gluu_session should has type Memcached

Based on this we need to create proper index in each bucket.

@nynymike @mbaser @afroDC Do you have any suggestions about this?

[yuriyz]

@yurem according to GluuFederation/oxCore#83 we need add Couchbase cache provider. I guess we need ou=cache bucket for it.

specify their type for optional performance.

Can you elaborate on how they can specify their type?

gluu (default)

I'm assuming this bucket will take everything not included in sessions, group/people, metric and site, right?

I implemented this by commit c34f217
However, current version of gluu is not working when additional buckets created, for this reason I commented them. Additionally:

1. we also need to identify which indexes should be created on each bucket,
2. determine how application ram will be distributed

Multiple buckets create works well with Couchbase 6.0.1
