Merge lp:~a1s/bzr-externals/breezy into lp:bzr-externals

[Aleksandr Smyshliaev]

Update for Breezy and Python3

- Change imports from bzrlib to breezy
- Use Python3 text file operations to read and write bzrmeta files
- Fix reading externals configuration from an InventoryTree
- Use command "brz ignore" instead of writing to IGNORE_FILENAME (Breezy doesn't export IGNORE_FILENAME)
