for successful notary request sending.
Add notary deposit on startup(and wait for
its acceptance). Add notary deposit timer,
its config in `morph` section and env vars
for its tuning.

Eigen trust block timer ticks to start new round of
eigen trust calculations. Every epoch this timer
recalculates duration and starts again.
