Controller: increase timeout of requests for units

[Tbaile]

Seems that if a unit has low connectivity, opening from the controller can be difficult due to low timeouts settings in the api server. The issue can easily be resolved by changing these values:

Released 1.2.4-dev.1

QA

1. Install stable version of controller and prepare a unit connected to it
2. Edit the /usr/libexec/rpcd/ns.controller file in the unit as follows (from line 113):

def info():
+  import time
+  time.sleep(3)
   ret = {"unit_name": "", "version": "", "subscription_type": "", "system_id": "", "ssh_port": -1, "fqdn": ""}

Now press "Open Unit" on the controller, this will cause an error.

3. Update the controller with the version provided above
4. Try again, the issue should be resolved.
