Ignore `ResourceWarning`

Ignore `ResourceWarning` to clear noise in logs until we replace `EdxRestApiClient` with `OAuthAPIClient`. We have too many warnings like this
unclosed <ssl.SSLSocket fd=33, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=6, laddr=('*.*.*', 47040), raddr=('*.*.*.*', 443)
