Add QoS configuration to RosNodeParams

[rafal-gorecki]

I really like this pkg and the way it was created. Bravo to the authors!

The only thing missing is the ability to set QoS for topics.
By the way, I also added the ability to change the qos_profile for services.

I found other solutions with similar themes, which may be updated if this PR passes:

• Allow override of QoS for RosTopicSubNode and RosTopicPubNode #14
• Make RosTopicSubNode a StatefulActionNode and handle different reliability QoS configurations #95

Hello @tony-p @facontidavide,
Can I ask one of u guys for review?

I'm not a maintainer so can't push this further. My first thought was why not define the qos in the node implementation as it will typically be constant for a particular message type, but on reflection I think adding to the params probably does make more sense.
