Deploying rubin-env 0.7.0

On Friday, 2021-08-13, we will update our build infrastructure to use version 0.7.0 of the rubin-env conda-forge metapackage. The w_2021_34 weekly will be the first one to incorporate this change.

This new environment adds the idds-doma and idds-client packages as requested in RFC-792.

rubin-env 0.7.0 should be used with all Science Pipelines code on or after d_2021_08_13. We believe it can be used successfully with all Science Pipelines code on or after w_2021_20. For older code or for v22, please use the appropriate version of rubin-env as defaulted in (Future versions of rubin-env will attempt to strictly comply with semantic versioning, but versions prior to 0.7.0 are not in strict compliance.)
