#### Why I did it
Fixing https://github.com/Azure/sonic-buildimage/issues/8938
Fixing 1x10G DPB mode in Mellanox-SN2700-D40C8S8 SKU as it was causing sonic-cfggen to fail.
#### How I did it
Added correct mode format in hwksu.json in Mellanox-SN2700-D40C8S8 and updated platform.json for the new mode.
#### How to verify it
Using sonic-cfggen verify it works fine
#### Why I did it
Current platform.json lacks some peripheral device related facts, like chassis/fan/pasu/drawer/thermal/components names, numbers, etc.
#### How I did it
Add platform device facts to the platform.json file

To fix [DPB| wrong aliases for interfaces](https://github.com/Azure/sonic-buildimage/issues/6024) issue, implimented flexible alias support [design doc](https://github.com/Azure/SONiC/pull/749)
> [[dpb|config] Fix the validation logic of breakout mode](https://github.com/Azure/sonic-utilities/pull/1440) depends on this
#### How I did it
1. Removed `"alias_at_lanes"` from port-configuration file(i.e. platfrom.json)
2. Added dictionary to "breakout_modes" values. This defines the breakout modes available on the platform for this parent port, and it maps to the alias list. The alias list presents the alias names for individual ports in order under this breakout mode.
```
{
"interfaces": {
"Ethernet0": {
"index": "1,1,1,1",
"lanes": "0,1,2,3",
"breakout_modes": {
"1x100G[40G]": ["Eth1"],
"2x50G": ["Eth1/1", "Eth1/2"],
"4x25G[10G]": ["Eth1/1", "Eth1/2", "Eth1/3", "Eth1/4"],
"2x25G(2)+1x50G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"],
"1x50G(2)+2x25G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"]
}
}
}
```
#### How to verify it
`config interface breakout`

[DPB] added capability files for SN2700 platform
- Why I did it
platform.json and hwsku.json files are required for a feature called Dynamic Port Breakout
- How I did it
Created capability files according to platform specification SN2700
- How to verify it
Full qualification requires bugs fixes reported under sonic-buildimage
NOTE: breakout to 4 is currently not available as of missing functionality in DPB implementation.

In order to build up device hierachy, PSU and module thermals are no longer child of chassis. PSU thermal belongs to PSU objects and SFP thermals belong to SFP object now. Need align this change in platform.json. Move thermal objects to correct parent device
As part of Platform api testing for multiple platforms, this pull request adds a platform.json file which contains all
the static data for Mellanox-2700 platform. This file would provide all the platform specific data required for testing of all the Platform tests . As part of testing the API's the values of static/default objects within this specific platform file will be compared against the values returned by calling the Platform specific API's in a typical platform test
