Raise the interpolation and obfuscation of commands to the OpenBAS platform level

[RomuDeuxfois]

Description

Now

• OpenBAS put it the job table with the command in plain text
• The signature mechanics, retrieve this command and encode it
• The implant retrieves this command, interpolates the arguments and encodes the command

Later

• OpenBAS feeds the job table with the interpolation and encoding of the command.
• The signature mechanics recover the command clearly and the command reworked.
• The implant retrieves the command directly reworked by OpenBAS.

Need to be done before #1604

@RomuDeuxfois : Does this issue concerns only payloads of type "command" ?

All payloads must be affected I think.
If we encode a drop file command, it should also be taken into account.
