Prevent run.sh from running beyond the first epoch under normal use (#4498)

Browse Source 
The local cluster that run.sh starts will typically only have a single
node, the bootstrap leader.  With epoch warmup enabled, run.sh will fail
after ~90 seconds once the warmup period has been exceeded due to lack
of votes from other validators.

As a workaround, disable epoch warmup and set slots-per-epoch to 1
million to keep run.sh alive for more than a fortnight.
