#### Why I did it Update scripts in sonic-buildimage from py-swsssdk to swsscommon #### How I did it Replace swsssdk with swsscommon in centec devices. #### How to verify it Pass all E2E test case #### Which release branch to backport (provide reason below if selected) <!-- - Note we only backport fixes to a release branch, *not* features! - Please also provide a reason for the backporting below. - e.g. - [x] 202006 --> - [ ] 201811 - [ ] 201911 - [ ] 202006 - [ ] 202012 - [ ] 202106 - [ ] 202111 - [ ] 202205 #### Description for the changelog Replace swsssdk with swsscommon in centec devices. #### Link to config_db schema for YANG module changes <!-- Provide a link to config_db schema for the table for which YANG model is defined Link should point to correct section on https://github.com/Azure/sonic-buildimage/blob/master/src/sonic-yang-models/doc/Configuration.md --> #### A picture of a cute animal (not mandatory but encouraged)
