Added no_scrub_restart flag to zpool reopen
Added -n flag to zpool reopen that allows a running scrub operation to continue if there is a device with Dirty Time Log. By default if a component device has a DTL and zpool reopen is executed all running scan operations will be restarted. Added functional tests for `zpool reopen` Tests covers following scenarios: * `zpool reopen` without arguments, * `zpool reopen` with pool name as argument, * `zpool reopen` while scrubbing, * `zpool reopen -n` while scrubbing, * `zpool reopen -n` while resilvering, * `zpool reopen` with bad arguments.
