Datacube

- Docs now refer to "Open Data Cube".
- Docs describe how to use ``conda`` to install datacube.
- Bug fixes for the stacking process.
- Minor model changes:
- Support for remote (non-file) locations from dataset objects: see 219
- Consistency improvents to the dataset properties: see 217
- Various other bug fixes and document updates.

This is the first release datacube-core, as part of the Open Data Cube community.


- Updated the Postgres product views to include the whole dataset metadata
document.

- `datacube system init` now recreates the product views by default every
time it is run, and now supports Postgres 9.6.

- URI searches are now better supported from the command line: `datacube dataset search uri = file:///some/uri/here`

- `datacube user` now supports a user description (via `--description`)
when creating a user, and delete accepts multiple user arguments.

- Platform-specific (Landsat) fields have been removed from the default ``eo``
metadata type in order to keep it minimal. Users & products can still add
their own metadata types to use additional fields.

- Dataset locations can now be archived, not just deleted.

This release now enforces the uri index changes to be applied: it will prompt
you to rerun `init` as an administrator to update your existing cubes:
`datacube -v system init` (this command can be run without affecting
read-only users, but will briefly pause writes)

- Implemented improvements to `dataset search` and `info` cli outputs
- Can now specify a range of years to process to `ingest` cli (e.g. 2000-2005)
- Fixed `metadata_type update` cli not creating indexes (running `system init` will create missing ones)
- Enable indexing of datacube generated NetCDF files. Making it much easier to pull
selected data into a private datacube index.
Use by running `datacube dataset add selected_netcdf.nc`.
- Switch versioning scheme to increment the second digit instead of the third.

- Added sources-policy options to dataset add cli
- Multiple dataset search improvements related to locations
- Keep hours/minutes when grouping data by solar_day
- CLI commands `datacube dataset info` and `datacube dataset search` now display more information and both support CSV or YAML output.
- Other minor bugfixes/improvements (~130 commits since 1.1.17)

Code Changes:
- `datacube.model.CRS,BoundingBox,Coordinate,GeoBox` have moved into `datacube.utils.geometry`

- Fixed several issues with the geometry utils
- Added more operations to the geometry utils
- Updated Code Recipes section to use geometry utils
- Enabled Windows CI (python 3 only)

- Added `update` command to `datacube dataset` cli
- Added `show` command to `datacube product` cli
- Added `list` and `show` commands to `datacube metadata_type` cli
- Added 'storage unit' stacker application
- Replaced `model.GeoPolygon` with `utils.geometry` library
