Improve syncying / indexing progress reporting when a node is starting or completed #152

• I have read the Contributing file of the documentation.
• I have searched the issues (including closed ones) and believe that this is not a duplicate.
• I am willing to lend a hand to help implement this feature.

Feature Description

The endpoints /syncing and /indexing only return a value indicating whether the node is syncing or not, and the syncing percentage.

I think they should return more information:

• Boolean 'isSynced' / 'isIndexing' indicating if the syncronization is 100%.
• Boolean 'isStarting' indicating if the node is starting (because if it is not syncing, and starting, we might think it is because an error).

The value 'syncing' should be true when the synchronization is completed, because the node is synchronized, but it is, in fact, still syncing.
