[WIP] Add a notice when we reach the max indexes of a mongo collection

Add a notice to prevent the following error when we install the PIM with Mongo and more than 64 indexes for values,

`Error #67 in class MongoResultException: localhost:27017: add index fails, too many indexes for pim_ce_mongo.pim_catalog_product key:{ normalizedData.completenesses.mobile-en_US: 1 }`

The new message is the following, it doesnt stop the install

`Too many MongoDB indexes (64), not way to add Array
(
    [0] => normalizedData.light_metering-de_DE
    [1] => normalizedData.light_metering-en_US
    [2] => normalizedData.light_metering-fr_FR
)`
