#### Why I did it

Facilitate Automatic integration of sdk kernel patches into SONiC. 

**Inputs to the Script:**
1) `MLNX_SDK_VERSION` Eg: `4.5.4206`
2) `MLNX_SDK_ISSU_VERSION` Eg: `101` 
 **Note: If nothing is provided the one already present in the sdk.mk file is used**
3) `MLNX_SDK_SOURCE_BASE_URL:` 
 **Note: If nothing is provided the upstream sdk drivers url is used**
4) `CREATE_BRANCH: (y|n)` Creates a branch instead of a commit (optional, default: n) 
5) `BRANCH_SONIC`:  Only relevant when CREATE_BRANCH is y. `Default: master`. 

Note: These should be provided through `SONIC_OVERRIDE_BUILD_VARS ` parameter

**Output:**
1) Script creates a commit in sonic-linux-kernel with any updates to sdk-kernel patches in sonic in accordance with the version provided by  `MLNX_SDK_VERSION`

**Note: Script Doesn't commit anything to linux-kernel when there aren't any changes required..**  

#### How I did it

1) Added a new make target which can be invoked by calling `make integrate-mlnx-sdk`

```
user@server:/sonic-buildimage/src/sonic-linux-kernel$ git rev-parse --abbrev-ref HEAD
master_6f38dca_integrate_4.5.4206

user@server:/sonic-buildimage/src/sonic-linux-kernel$ git log --oneline -n 1
d64d1e7 (HEAD -> master_6f38dca_integrate_4.5.4206) Intgerate MLNX SDK 4.5.4206 Kernel Patches
```

Changes made will be summarized under `sonic-buildimage/integrate-mlnx-sdk_user.out` file. Debugging and troubleshooting output is written to `sonic-buildimage/integrate-mlnx-sdk.log` files

#### Limitations:
1) Assumes that the sdk kernel patches are always upstreamed

#### How to verify it

Build the Kernel and test
