Since !392 we must format the json as done by `format-json`.

The tools for this are `format-json software/*/*.json` or `husky` ( !424 ).

Since Caddy 0.11.1, certificates has to match sites
(Thanks Luke)

trafficserver-cache-availability.py may pass randomly, as we do not have a
way during the test to really fill it.

As some of the nodes can lag behind, the system can be in state, that those
nodes will send inactive (also destroyed) slave publish information. Before
publishing it to master, check if each of slaves is really present on master.

Tasks:

 - [x] prove it really works on simulated environment
 - [x] check impact on massive simulated environment
 - [x] cover with a test (optionally)
 - [ ] check test results with this change

OPENSSL_BINARY is not needed in the test case, only SQLBENCH_PATH has to be
provided, and perl shall be available in the PATH.

 * The service-auto-approve-amount to default is set to 1, in order that the
   only needed service is automatically approved.  As caucase is accessed
   internally (on local IPv4) only partitions on the same server will access
   caucase.

  This commit add srsLTE into slapos. More informations about
  srsLTE at: https://github.com/srsLTE/srsLTE

  This still a proof of concept because:

   - Not all dependencies are ported into slapos
   - The configuration files are not turned into parameters
   - enb and epc are running on the same partitions
   - Usage of sudo is a code crime, but it is the only way currently**

** This would require patch the srsLTE, to allow external tools pre-configure
  the environment. ie.: Create network interface.

Use json.dumps/.loads to generate promise plugin code. This is safe as it will correctly escape sring and prevent code injection from untrustable parameters.

Add 'import' parameter to simplify parameters used to generate the script instead of passing full import code. When import parameter is set, promise will be loaded from that import path and parameter `content` is ignored.
