Remove extraneous template data

[aquarat]

This PR removes the following fields from the deployed templates:

• templateName
• description
• parameters (which were encoded parameters)

It also renames decodedParameters to parameters.
We retain templateName and description in the beacon files.

Also removes the erroneous 'mumbai' chain from chains.json, per issue #10

Beacons should have an encoded parameters field as described here but they should be "0x" if we're not specifying any overriding parameters

[bbenligiray]

Template parameters were correct before the PR, there needs to be an encoded parameters and a decoded decodedParameters field

[wkande]

Just to be clear, will any filed names change in data/documentation_metadata.json. If they do I need to change the docs since it reads from this file in real time.

Thanks, it's all good now. I think this doesn't change data/documentation_metadata.json so you shouldn't need to change anything for this PR specifically. However, we should address api3dao/services#17 in a separate PR and then you will probably need to read beaconName from that JSON.

Yes, thanks for this and apologies for it taking me so long. I specifically tried to not make any changes to documentation_metadata.json so as to avoid consumers from being disrupted.
