allow to execute actions for file operations and SSH commands synchronously 
The actions to run synchronously can be configured via the `execute_sync`
configuration key.

Executing an action synchronously means that SFTPGo will not return a result
code to the client until your hook have completed its execution.

Fixes #409

fix a potential race condition for pre-login and ext auth 
hooks

doing something like this:

err = provider.updateUser(u)
...
return provider.userExists(username)

could be racy if another update happen before

provider.userExists(username)

also pass a pointer to updateUser so if the user is modified inside
"validateUser" we can just return the modified user without do a new
query
