[UWS,TAP] Review the standard parameters checking. Particularly, because before, the default value was never used while no value was specified by the user.

[TAP,UWS] Fix a problem with the format of the error details returned by the parameter .../error/details. In TAP a VOTable document is expected, but a text/plain description was returned (default behavior in the UWS lib.). Now, a ServiceErrorWriter is used to format the error details correctly.

[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

[TAP] Remove all generic types + Delete specific (for ResultSet) output formatters + Modify the main output formatter
