Removed the "Issues for 201911" label, as this platform is not supported in 201911; in fact support for this platform is not yet even included in the master branch (it is currently in pull request here).

@Junchao-Mellanox: Can you please investigate this thermalctld exception and why there is no error message appended to the message? Support for the platform in question is currently under pull request here.

Also, it appears this message is also seen on other platforms.

Will create a PR to fix this. The issue is at line:

self.log_error('Caught exception while initializing thermal manager - {}'.format(e))

Need change it to:

self.log_error('Caught exception while initializing thermal manager - {}'.format(repr(e)))

And i need also catch the NotImplementedError and log a warning message.

Fixed via sonic-net/sonic-platform-daemons#103 (submodule updated in #5741).
