llc-management: Support for LLC management with RMD

This patch adds support for LLC-Last level cache
management using RMD. The changes include:
1. 08_llcmanagement.conf: The configuration file to define cache
allocation policy.
2. testcase.py: To trigger llc-allocation and cleanup before and
after the test, respectively.
3. llc_management/rmd.py: The main file the performs the llc
allocation and cleanup.
4. llc_management/resthttp.py: Generic utility to call rest APIs,
with http.
5. Fixed a build error due to change in name mismatch.
6. Fixed pylint errors. Override built-in function error.
7. Added empty __init__.py to avoid import errors
8. Fixed deprecated functions errors
9. Fixed copyright issues, removed python-3 checking.
10. Removed pylint disables.
11. resthttp.py is already part of stcrestclient used in
tools/pkt_gen/testcenter/ scripts. Hence, deleted from the source.
12. Year update from the license
13. Fixed some testcases.py collision issue
