Update git submodules

* Update docs/submodules/clover from branch 'stable/gambia'
  - Merge "CLOVER-43: Initial commit for Clovisor" into stable/gambia
  - CLOVER-43: Initial commit for Clovisor
    
    Part of Clover's initial task (during project proposal) is to explore
    cloud native network tracing tools. Clover the project proposes
    Clovisor as a way for Clover to use the IOvisor
    (https://www.iovisor.org/) to perform network tracing. This is the first
    commit of this module
    
    Please note that the BPF code used in this commit were only tested with
    Linux kernel 4.14+ --- hence, if ubuntu is used, and one prefers LTS,
    the requirement is 18.04+
    
    A different patch will track the redis and k8s API server watcher code
    
    Also, a design doc will be added in the future (TBD)
