Rewritten L2TP to get_config_dict
Rewritten L2TP xml to accel-ppp patterns
Migrated 'idle' to 'ppp-options.lcp-echo-timeout'
Migrated 'authentication.mppe' to 'ppp-options.mppe'
Migrated 'authentication.radius.dae-server' to
'authentication.radius.dynamic-author'
Migrated 'authentication.require' to 'authentication.protocol'
Added 'authentication.radius.acct-interim-jitter'
Added 'authentication.radius.preallocate-vif'
Added 'authentication.radius.server.<IP>.acct-port'
Added 'ppp-options.ipv4'
Added smoke-tests
