Deprecated call to yaml.load

[jgbarah]

When launching sirmordred with any configuration, you see two warnings:

Starting SirMordred to build a GrimoireLab dashboard
This will usually take a while...
/usr/local/lib/python3.5/dist-packages/sirmordred/task_panels.py:180: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
  self.panels_menu = yaml.load(f)
/usr/local/lib/python3.5/dist-packages/sirmordred/task_panels.py:437: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
  self.panels_menu = yaml.load(f)

I think the fix is easy: just call yaml.load() with a Loader parameter.

I know this is not exactly a bug, since it produces the right output. But I'm labeling as bug because it is kindda confusing for the user, anyway...

The fix should be similar to the code in this PR: chaoss/grimoirelab-sortinghat#200

@sumitskj this could be good for you for micro-task 9, what do you think ? :)

Sure, I will try to fix this

I have added the Loader param in yaml.load() #289 but it has failed to pass tests. Can you see this @jgbarah @valeriocos .

[valeriocos]

Thank you for working on this issue @sumitskj .The tests fail due to a missing package. I'll make a local test and merge it

Merged, thank you @sumitskj
