3.2 internal indices config

[havidarou]

Hello,

this PR adds the possibility to use different shard and replica configuration for both .wazuh and .wazuh-version indices.

This are the options in the config.yml file:

#--------------------- Indices configuration ------------------------------------
#
# Configure .wazuh and .wazuh-version indices shards and replicas
#wazuh.shards              : 1
#wazuh.replicas            : 1
#wazuh-version.shards      : 1
#wazuh-version.replicas    : 1

Keep in mind that for it to work, the configuration file must be appropriately edited prior app installation.

Regards.
