1. The test step for error code REASON_ASSOC_EXPIRE is not reliable. SoftAP
could also send error code WIFI_REASON_NOT_AUTHED
2. STA will be disconnected now if softAP restart DHCP server
we'll auto assign cases to test jobs so we don't need those config
files. cases with different wifi modes will now be generated when
creating test case database, we need to remove them from YAML files.
1. (^)TCPIP_DHCP_0101, (^)TCPIP_DHCP_0301: IDF set IP 0.0.0.0 may return error, don't check the result of setting IP to 0.0.0.0;
2. rename (^)TCPIP_DHCP_0102 to (^)TCPIP_DHCP_0212 as it's a DHCP server test case;
3. (^)TCPIP_TCP_0204,(^)TCPIP_TCP_0210,(^)TCPIP_UDP_0201,(^)TCPIP_UDP_0202: recv thread can't be deleted, change case to not create recv thread when create socket ;
4. (^)TCPIP_TCP_0206,(^)TCPIP_TCP_0212: query TCP server status format changed.
5. WIFI_SCAN_0301: check command error and test environment not correct
6. WIFI_SCAN_0302, WIFI_SCAN_0303, WIFI_SCAN_0304: test environment not correct
1. unsupported cases by "phy" command
2. DHCP server behavior different from ESP8266
3. TCP failed cases causes by unstable TCP behavior
4. UDP failed cases by poor UDP performance
1. test will be categorized by test level
2. add test level as attribute to test cases
3. will select TestCaseScript by the test cases added to CI (currently no test case uses test case script)
4. adding test level to test jobs
5. update .gitlab-ci.yml, each job need to set its test case file path
6. update .gitlab-ci.yml, test case path for test report is changed to idf_test
