Page Provider Configuration

Goal is to be able to declare from Studio a pageprovider that one can use and reference from the REST API. Currently one has to create a content view for declaring a page provider with Studio, which doesn’t make sense as you may want to use one for instance just to have a parameterized query and not a hardcoded in your java code, or because you use it on a custom remote application through REST API.

It should be possible to configure:

• the type (coreQuery, Elasticsearch, CMIS,Audit, custom, give the class)
• the where clause / fixed part
• the where clause / predicates * (is it equivalent to the named parameters ?)
• Aggregates for ES ones
• Sort criterias
• Fixed Parts
  Some parameters values:
• maxSize
• pageSize
• maxResults (!!!)

For editing the predicates we could use the schema editor inteface as it is pretty simillar to it.

-... ? to be reviewed/ completed by @anahide and or Benoit Delbosc or Guillaume Renard (maybe with a few extensive contributions as a sample)

• mockups to be done after that
