DCausse has uploaded a new change for review. (

Change subject: Use the _aliases endpoint for fast index names retrieval
......................................................................
Use the _aliases endpoint for fast index names retrieval
When calling Cluster::getIndexNames() Elastica appears to fetch
unneeded information from the cluster. This results in a slow query
when this extension is used with a cluster that has many indices.
Use the _aliases API endpoint with wildcard expansion to speed-up this
process.
