[Backup] Restore options description is a bit ambiguous.

Restore options in the docs are documented with 2 fields: Constraints and Description.

The default value of these options is set as True.

The Description for these restore options seems a bit ambiguous , for example taking Analytics: https://docs-staging.couchbase.com/operator/current/resource/couchbasebackuprestore.html#couchbasebackuprestores-spec-services-analytics 

The description given for Analytics is:

Analytics maps to cbbackupmgr option --disable-analytics. 

and with default value as True , the general understanding of the option suggests the flag --disable-analytics is enabled by default. 

This holds true for all restore options. 

The docs should reflect that these options when not mentioned/set triggers the corresponding disable flag.
