**- Why I did it**
- Skip thermalctld in DellEMC S6000, S6100, Z9100 and Z9264 platforms.
- Change the return type of thermal Platform APIs in DellEMC S6000, S6100 and Z9100 platforms to 'float'.
**- How I did it**
- Add 'skip_thermalctld:true' in pmon_daemon_control.json for DellEMC S6000, S6100, Z9100 and Z9264 platforms.
- Made changes in thermal.py, for 'get_temperature', 'get_high_threshold' and 'get_low_threshold' to return 'float' value.
