discover: support 3 options to run APR when BMC is rebooted

As defined in the PDIs [1], the RebootCause can be
Power-On-Reset, Watchdog, Pinhole, Software or Unknown. When BMC is
rebooted due to Power-On-Reset, BMC always runs APR feature. But other
RebootCause values, we don't have a clear specification to indicate the
behavior of BMC in those cases. This commit adds 3 more options to
support running APR when BMC rebooted or not.
  - 'run-apr-on-pinhole-reset': Run APR when BMC is rebooted due to
    pinhole action.
  - 'run-apr-on-watchdog-reset': Run APR when BMC is rebooted due to
    watchdog.
  - 'run-apr-on-software-reset': Run APR when BMC is rebooted due to
    software.

Tested:

Test case 1:
   1. Enable run-apr-on-watchdog-reset option
   2. Trigger watchdog to reboot BMC
   3. BMC runs APR when booting done
   4. Disable run-apr-on-watchdog-reset option
   5. Trigger watchdog to reboot BMC
   6. BMC does not run APR when booting done

Test case 2:
   1. Enable run-apr-on-software-reset option
   2. Call "reboot" command to reboot BMC
   3. BMC runs APR when booting done
   4. Disable run-apr-on-software-reset option
   5. Trigger watchdog to reboot BMC
   6. BMC does not run APR when booting done
