[201911] [Mellanox] Update SAI to 1.16.6, SDK to 4.4.1014, FW to *.2008.1032

[keboliu]

- Why I did it
SAI changes:

Fix ECMP max groups logic
add set issu log level for spc2/spc3, as now issu is supported
set vlan max swid = 0 on sdk init, as only single swid is needed, for efficient resource usage
Fix traffic lost during FFB related to buffer config + optimize buffer config timing for FB
Add ACL fields BTH, IP flags
Add ACL infrastructure of different fields per ASIC type
Add port stat ether rx/tx oversize pkts

SDK/FW changes:

Added support for Finisar 100GbE SWDM Transceiver FTLC9152RGPL.
Spectrum-2 Added support for 10G BaseT modules
Added link LED support for SN4600C.
Counters | In SDK debug dump, the incorrect counter type appears for vtraps.
WJH | Without any traffic or events on the idle system, the CPU load is constantly above 4%
WJH | WJH filter currently cannot filter by PORT for buffer drop reason.
Spectrum | ACL, Unbind, Lazy Delete | Running Lazy Delete together with auto_unbind may cause rate condition errors. To work work with Lazy Delete use new INIT parameter "acl_manual_unbind" so that ACLs will notbe removed automatically when binding point is deleted.
Spectrum | ISSU | In ISSU mode, when querying for the number of configurable buffers, using the API sx_api_cos_port_buff_type_get with the count parameter as 0, the API returns the number for NORMAL mode instead.
Spectrum-2 | BER | BER monitor counts raw errors instead of effective errors
Spectrum-2 | BER | Connecting to ConnectX-5 adapter card with copper splitter cable MCP7H50-V001R30 in 1
Spectrum-2 | Cables | Link flaps in 200GbE with AOM Optic cable MMA1T00-VS
Spectrum-3 | Speeds, Link | When moving from a 400GbE link to a 1GbE link, packets may drop for 1msec right after link up
Spectrum-3 | Cables, Speeds | Using 400GbE with 3rd party systems is not supported
Spectrum-3 | LAG | After a while, LAG members become out of sync with one another
Spectrum-3 | VLAN, Ports | Packets with VLAN headers are sent to
