Subject: Add support for Entity Association Record

Adding support for Entity Association Record (SDR type - 0x08h)
This patch includes:
1) Entity Association Record yaml file example
2) Entity Assocation Record related script and mako file changes
3) Adding Entity Association Record in get_sdr IPMI command response

From the host, tested that entity association records can be fetched
