manifest creation helper

[shadeofblue]

Add helper API for manifests,

Based on the schema described in GAP-4:
https://github.com/golemfactory/golem-architecture/blob/master/gaps/gap-4_comp_manifest/gap-4_comp_manifest.md
and GAP-5
https://github.com/golemfactory/golem-architecture/blob/master/gaps/gap-5_payload_manifest/gap-5_payload_manifest.md

implement a Manifest class that:

• creates an internal, object representation of the Manifest
• populates the representation with all elements that are able to be added automatically and are required by the schema
• allows the user to modify the manifest interactively (e.g. add outbound urls)
• enables serialization of the manifest
• provides a helper to do all of the above easily, e.g.:

manifest = Manifest(image_hash="sha3:05270a8a938ff5f5e30b0e61bc983a8c3e286c5cd414a32e1a077657", properties={"net.inet.out.urls": ["http://bor.golem.network"]})

the defaults to be used:

{
    "version": "",
    "createdAt": [ CURRENT DATE TIME ],
    "expiresAt": "2100-01-01T00:01:00.000000Z",

          "os": "linux"
        },
        "urls": [ BASED ON THE RESOLVED VALUE FROM THE HASH - or through a directly provided value],
        "hash": [ (for now) MUST BE PROVIDED BY THE USER, may change when we switch to using tags ] 
      }
    ],
    "compManifest": {
      "version": "",

[ only "run" allowed by default, user may, of course override this ] 

      "script": {
        "commands": [
          "run .*",
        ],
        "match": "regex"
      },

[ "net" section not included by default - must be constructed when a user passes a list of URLs] 

    }
}
