Anton Kaliaev c56fd04ab4 lite2: disconnect from bad nodes (#4388)
Closes #4385

* extract TrustOptions into its own file

* print trusted hash before asking whenever to rollback or not

so the user could reset the light client with the trusted header

* do not return an error if rollback is aborted

reason: we trust the old header presumably, so can continue from it.

* add note about time of initial header

* improve logging and add comments

* cross-check newHeader after LC verified it

* check if header is not nil

so we don't crash on the next line

* remove witness if it sends us incorrect header

* require at least one witness

* fix build and tests

* rename tests and assert for specific error

* wrote a test

* fix linter errors

* only check 1/3 if headers diverge
