Test pipeline (#12)

* Fix memory leak issue in ConfigDBConnector. (sonic-net#655)

#### Why I did it
Fix memory leak issue in ConfigDBConnector:
[chassis] Too many open files error and unable to connect to redis socket error
sonic-net/sonic-buildimage#10870

The reason of this issue is DBConnector::pubsub() will return a pointer, and following code call this method but never release the returned pointer:

```
void ConfigDBConnector_Native::db_connect(string db_name, bool wait_for_init, bool retry_on)
{
    m_db_name = db_name;
    m_key_separator = m_table_name_separator = get_db_separator(db_name);
    SonicV2Connector_Native::connect(m_db_name, retry_on);

    if (wait_for_init)
    {
        auto& client = get_redis_client(m_db_name);
        auto pubsub = client.pubsub(); <== this pointer not delete later.
```

Also change DBConnector::pubsub() to deprecated for none SWIG scenario.

#### How I did it
Change DBConnector::pubsub() to return a smart pointer.

#### How to verify it
Pass all test case.

Run following code in python and validate there is no epoll and socket leak:
```
import gc
from swsscommon import swsscommon
config_db = swsscommon.ConfigDBConnector_Native()
config_db.connect()
config_db.connect()
config_db.connect()

gc.collect()
```
