This introduces a new `state` column in `software` table.

Because node already has support for reporting various states of software
lifetime, this implementation stores the actual state of the software
installation.
What's not clear is that maybe it should store the requested state and the current state.

```plantuml
@startuml
start
repeat
  -> client request software in state available \n ""supplySupply?state="available""";
  if (already available ?) then (yes)
    :available;
  else (no )
    :install_requested;
    -> node starts building \n ""buildingSoftwareRelease"";
    :building;
    if ( build result? ) then ( node report build successful \n ""availableSoftwareRelease"" )
      :available;
    else (node report build error \n ""softwareReleaseError"" )
      :error;
    endif
  endif
repeat while ()

-> client request software in state destroyed \n ""supplySupply?state="destroyed""";;
:destroyed;
-> node notify software is deleted \n""destroyedSoftwareRelease"";
stop
@enduml
```

By just taking action "destroy" where requested state is destroyed and
installing for all other states, we can inform master of the state.
XXX this is wrong !

This will let the connection parameters with multilines value be correctly displayed.

I also fixed the linter.

slapos_crm: testSlapOSCRMSkins: The order of the elements of portal_catalog are not always the same.

Probably incomplete as we need to check for activities.

[slapos_crm] fix failing crm skins tests after include error message in generated ticket for hosting subscription

After c931d60c, default options were changed and we didn't want that.

Rewrite the code so that we have a clearer scheme:
 * all options of format are listed as FormatConfig attributes with default values
 * all values present in configuration file (.cfg) erase the previous options
 * all values present in command line erase the previous options

We use the special default argparse.SUPPRESS that removes totally the arg from arg dict so that only PRESENT options erase something

fix after !62

@rafael currently slapos node boot is broken on all machines with ipv6_interface different from interface_name (e.g. rapid space machines)
