[BREAKING] fxconfig: create MSP-based namespace policies (#59)

#### Type of change

- Bug fix
- New feature
- Improvement (improvement to code, performance, etc)
- Test update
- Documentation update
- Breaking change

#### Description

This PR introduces MSP-based namespace policies and adds new commands.
We also bump the committer version from `v0.1.8` to `v0.1.9`.

Summary
- The `--channel` flag was removed. 
- The `--policy-ecdsa-threshold` flag was replaced by `--policy`.
- Add `--wait` flag 
- Add `tx endorse` command
- Add `tx merge` command
- Add `tx submit` command

For the full documentation see the new README.md in
`tools/fxconfig/docs/`

Note that the CLI API may still change until next release.
