[IMPACT]
When running the ovn_central plugin on a non-leader host the sbctl command hangs indefinitely until the sosreport timeout kicks in.

[TEST CASE]
* Run 'sos report -a' (AKA sosreport -a) which should exercise ovn-central, if the detection criteria are met. In this case if package 'ovn-central' is installed.

AND/OR

* Run 'sos report -o ovn_central' (AKA sosreport -o ovn_central) which
will enable the ovn_central plugin only.

* The plugin will then timeout and logs will be as follows:

[plugin:ovn_central] collecting output of 'ovn-nbctl show'
[plugin:ovn_central] collecting output of 'ovn-sbctl show'

[WHERE PROBLEM COULD OCCUR]

If something arise after this change. It will only affect the data
collection of the ovn-central plugin individually. It won't affect other
plugins nor core functionalities.

Worse case scenario would be that user will have to collect ovn
debugging data manually (outside a usual sosreport run) in order to
provide it to a third-party support vendor.
