v0.17.0

This release replaces the previous v0.16.0, which was affected by a bug that prevented the sending of BitSong tokens via IBC.

This is a manual coordinated upgrade that will happen at block 18,338,000 expected August 22nd, 12:30:00 UTC.

Validators are required to halt the chain at that block, and then apply the v0.17.0 upgrade.

2. Restart your node to apply configuration changes.
3. Make sure your systemd file is set to restart=no otherwise the node will not stop
4. Wait for block 18338000, at which the chain will stop
5. Build the tag v0.17.0
6. Remove the halt height from configuration
7. Restart the node
