CLI/Tooling update

[myitcv]

The cue command just received a major update with release v0.1.0. There are still various thing that this release prepare for, but were left unaddressed:

In the shorter term we intent to target the following:

• new "default" command, invoked by just cue, replacing eval and making export and def special cases.
• cue test to test CUE packages and cue tool commands.
• cue diff/snapshot for comparing between two CUE versions.
• cue run a more sensible rewrite of cue cmd.
• The latter may include what constitutes a tool file and local import of packages.
• Support for dowload of OpenAPI and JSON Schema references in cue import/get
• Allowing builtin tooling layer functions (not just task types) to allow implementing a filepath package as well as other functionality.

More medium term targets:

• MVS implementation for CUE modules, allowing versioning and importing of CUE packages analogous to Go.
• Task type to allow writing Go functions in the CUE tooling layer, automatically converting CUE types to equivalent Go.
• Generic task adaptor support.
• More dynamic task evaluation, allowing dynamically created tasks.

Optional:

• User-defined flags. This may not be needed with the addition of --inject support.
• "Merging" of packages on the command line, for instance using the -m flag. It is not entirely clear what the semantics should be there and if it is a good idea at all.
