Docker slim session

[wtgee]

Clean up the repo so that it can act as a good base for docker services, but don't provide any actual services in the repo.

From the changelog:

Added ^^^^^

• Conda environment file
• A cli script for panoptes-utils. This will eventually take over the panoptes-config-server and any other simple commands needed. For now can use panoptes-utils tests run for building and running tests.

Changed ^^^^^^^

• Updated testing to use specific docker image. Updated run script for more specific options on starting testing config server.
• Different extras install options: config, docs, images, testing, and social.
• Use loguru for logging directly in all files, rather than needless import.

Fixed ^^^^^

• Plate solving extras option parsing correctly.
• Explicit imports for some of the utils.

Removed ^^^^^^^

• Remove Docker services except for testing.

• Removed unused files:

  • Example data fetching notebook removed.
  • Hotspot script removed.
  • Data (astrometry index and IERS) download removed.
  • wait-for-it.sh script removed.
  • TheSkyX utils moving to POCS directly.
  • Removed moving_average.
  • Removed pipeline functions for getting image_id and sequence_id.
