wow Daniel, you've been busy ;)

nice!!!!

thanks, still a bit to tune it (add the feature of enable/disable connections), but should be workable as it is. Couldn't test all scenarios, so feedback would be welcome!

Cheers, Daniel

db_cluster: new module for generic database clustering

- the module allow to group several DB connections and perform
commands
 over them, based on policies such as round robin, serial try or
 parallel execution
- any kind of db connection can make part from a cluster
- example use case: write in parallel to two databases and do round
 robin read from them
- the module is a middle layer between modules and databases, reusing
 existing db connectors. A module that wants to use such cluster, just
 have to set the db_url to "cluster://clusterid"
- the module allow definition of multiple clusters
- see README for more details
- todo: enable/disable connections at runtime and via rpc
