Bug 1657649 - [taskgraph] Remove the SETA optimizer, r?jmaher

SETA is currently used as:

  1. A shadow scheduler (to use as a baseline comparison)
  2. A fallback in case bugbug times out on autoland

Neither is necessary, for 1 the 'relevant_tests' optimizer performs very similarly and can become the new baseline.

For 2, timeouts have become much less frequent and we can fallback to relevant_tests (or just schedule nothing) instead.
