Fix first time grant failure bug

[kentbull]

This does a few things with the most important being upgrading to GLEIF-IT/keripy 1.2.8 including the exchange message processing fix

Other parts:

1. Cleaned up imports
2. Cleaned up logging with consistent root level module ogler usage and pulled in the TruncatedFormatter from vLEI-Server and KERIA.
3. Refactored server setup to return a list of Doers so using it from an end-to-end system simulation test in SignifyPy is easy.
4. Added a config bootstrapper so that sally server start ... is all you have to do, like the following command:

sally server start \
  --direct \
  --http 9723 \
  --salt 0AD45YWdzWSwNREuAoitH_CC \
  --name sally \
  --alias sally \
  --config-dir scripts \
  --config-file sally.json \
  --incept-file sally-incept.json \
  --passcode VVmRdBTe5YCyLMmYRqTAi \
  --web-hook http://127.0.0.1:9923 \
  --auth EMCRBKH4Kvj03xbEVzKmOIrg0sosqHUF9VG2vzT9ybzv \
  --loglevel INFO
