Allow to preset timeout for connection on coral-supported Databases

[ggovi]

PR description:

We are adding the access to the coral connectionTimeout parameter, to allow to preset values in the read-only workflows based on ESSource. Default value is 0=> no pool of idle connection.

The effect has been tested on Hilton for the HLT workflow. No visible performace change observe, but clear decrease of File descriptor opened ( the previous default value was 300 seconds )

Unit and integration test of CondCore packages are ok.
