[UWS,TAP] Add clean release of all resources (e.g. Threads, Timers, DB connections) allocated in a UWS and a TAP service. Small changes of the UWS API...but only if ExecutionManager, DestructionManager and UWS have been implemented by library users rather than using the default implementation.

[UWS,TAP] Review the exceptions and logs management + Add log file rotation (with a configurable rotation frequency)

[TAP] Remake TAPFactory into an abstract class + let limit the number of jobs (async and sync) by allowing the TAPFactory to communicate with a connection pool
