Add options in hostapd to inject connection failures.

Add hostapd_cli set commands for skip_send_eapol and enable_eapol_large_timeout.
1) with skip_send_eapol=1, AP won't send m0/m2 frames.
2) with enable_eapol_large_timeout=1, AP will time out 50 seconds after m0 or m2.
These two flags can also be set in hostapd.conf. By default, both are
set to 0.

With skip_send_eapol=1 and enable_eapol_large_timeout=0, AP will deauthenticate STA during 4-way handshake.
With skip_send_eapol=1 and enable_eapol_large_timeout=1, STA will hit auth timeout.

Bug: 174201865
Test: manual test with hostapd_cli set commands and check if STA hits
the above connection failures.
