Adding dist and nodemanager repos to softwareupdater

[asm582]

Currently softwareupdater has the following files:-

-rw-r--r-- 1 clienttuf clienttuf 31189 Apr 26 23:20 softwareupdater.py
drwxr-xr-x 2 clienttuf clienttuf 4096 Apr 26 23:20 scripts
-rw-r--r-- 1 clienttuf clienttuf 654 Apr 26 23:20 generatekeys.py
-rw-r--r-- 1 clienttuf clienttuf 4543 Apr 26 23:20 writemetainfo.py
drwxr-xr-x 2 clienttuf clienttuf 4096 Apr 26 23:20 test

can we add dist and nodemanager repository as it uses preparetest.py of dist and runonce.py of nodemanager repo to create a local softwareupdater repository.
