[mellanox] Facilitate automatic integration of new hw-mgmt

[vivekrnv]

Why I did it

Facilitate Automatic integration of new hw-mgmt version into SONiC.

Inputs to the Script:

1. MLNX_HW_MANAGEMENT_VERSION Eg: 7.0040.5202
2. CREATE_BRANCH: (y|n) Creates a branch instead of a commit (optional, default: n)
3. 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 each of sonic-buildimage, sonic-linux-kernel) with all the changes required for upgrading the hw-management version to a version provided by MLNX_HW_MANAGEMENT_VERSION

Brief Summary of the changes made:

1. MLNX_HW_MANAGEMENT_VERSION flag in the hw-management.mk file
2. hw-mgmt submodule is updated to the corresponding version
3. Updates are made to non-upstream-patches/patches and series.patch file
4. series, kconfig-inclusion and kconfig-exclusion files can be updated in the sonic-linux-kernel repo
5. sonic-linux-kernel/patches folder is updated with the corresponding upstream patches
6. Based on the inputs, there could be a branch seen in the local for each of the repo's. Branch is named as <branch>_<parent_commit>_integrate_<hw_mgmt_version>

How I did it

1. Added a new make target which can be invoked by calling make integrate-mlnx-hw-mgmt

user@server:/sonic-buildimage$ git rev-parse --abbrev-ref HEAD
master_23193446a_integrate_7.0020.5052
user@server:/sonic-buildimage$ git log --oneline -n 2

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

Jenkins output file:

stdout for debugging:
http://nbu-nfs.mellanox.com/auto/mtrsysgwork/vkarri/integrate-mlnx-hw-mgmt.log

Limitations:

1. Assumes the changes would only work for amd64
2. Assumes the non-upstream patches in mellanox only belong to hw-mgmt
