[r=dimitern],[bug=1257649] bootstrap: Added configurable timeout and delays
Fixed bug #1257649: ssh timeout for bootstrap
could be configurable, by adding 3 new config
settings:
- bootstrap-timeout (default: 600s = 10m)
- bootstrap-retry-delay (default: 5s)
- bootstrap-addresses-delay (default: 10s)
All of them are integers, measured in seconds,
and also all of them are optional and have the
specified defaults.
Updated the bootstrap command's help text to
include the new config settings.
