In order to do tag mapping we need to have a clear and clean way to store the original source tags (Tags from the provider) and the target tags (New tag that the source tag will be mapped to)

Things to consider:

• Target tags MUST be Source tags (meaning you can't create arbitrary tags)
• Multiple Source tags can be mapped to the same Target tag
• source/target mappings should consider cost model relations (if a tag key is part of a cost model we should at minimum tell the user which cost model is affected if a source/target relation is updated)
• List of source tags are built from Enabled tags only
• Disabling a source tag that has been mapped to a new target tag should at minimum show a warning with its relation and result
• Disabling a source tag that IS a target tag should show a warning that lists all the source tags that will be change from losing that target tag relation
