Mongodb complains about not being master on primary mongo

[Sergey Yudin]

Fuel Version: 5.1.1

Way to reproduce: NA, appears randomly

Description:
When mongo first starts up it calls for election(even with single node) and if we will start configureing mongo we will get something like:

Proposed solution:
We need to wait till node will finish the election and will become master even in single node replset before starting messing around with mongo.

Trying to get review on https://review.openstack.org/#/c/161753/

[Sergey Yudin (tsipa740)]

Should i do same patch for 5.1 and 6.0 branches?

[Bartłomiej Piotrowski (bpiotrowski)]

Let's wait until your patch hits master branch.

[Sergey Yudin (tsipa740)]

It finally passed tests and got some reviews.

Guys, how i can proceed with this to get it merged?

    Waiting for mongo elections

    We need to wait till node will finish the elections
    and will become master even in single node
    replset before proceeding with Mongo configuration.

It still does not work on envs with single mongo node because we're getting empty array here:

https://github.com/stackforge/fuel-library/blob/master/deployment/puppet/osnailyfacter/modular/roles/mongo_primary.pp#L16

It's happenning because with single mongo node we have no 'mongo' roles, only one 'primary-mongo' role. If I understand correctly, we're supposed to get an array of all mongo nodes (primary-mongo and mongo roles) there.
