feat: Support OTA update/check all devices

Could we also introduce a device_options to ignore OTA for a device or exclude it from the update_all?

update_all seems very useful but there is one device I don't want to update. I expect I might not be the only one.

A few ideas:

• Change frontend OTA page to have checkboxes in front of each device => check all/update all can send the list of network addresses of checked devices to MQTT, then Z2M acts for these only.
• Ensure a failed update doesn't break the rest of the sequence. Also probably best to delay a bit in that scenario in case the device rebooted or something...
• Make IMAGE_BLOCK_RESPONSE_DELAY configurable https://github.com/Koenkk/zigbee-herdsman-converters/blob/423305d36cba7bf45d158b2025fa832e9b023668/src/lib/ota/common.ts#L54
  • See about implementing the missing ZCL stuff for OTA 11.13.8.2.9 MinimumBlockPeriod, 11.15.3 Rate Limiting, which could possibly have better results for supporting devices (device throttles itself, instead of being unaware that Z2M is throttling responses). Might also be able to remove the limitations of some devices that take forever to update because they request images at a very slow rate (I'm assuming that's the property they are using).
• Add an OTA blocklist setting to always reply "no" whenever these devices request "check for new firmware" (even if one is available).
