Relates to #44

- perform module migration to add the photon module in the upgrade
module version map
- register the photon denom metata in the bank module
- add a storeloader for the photon module (required for all new modules)

Relates to #44 

This PR adds a `sdk.AnteDecorator` implementation in `x/photon/ante` and
adds it to the list of the app ante decorators. This new ante decorator
ensures that photon is the fee token or returns an error. Exceptions are
possible like if the transaction's messages type URL are present in a
new parameter of the photon module `txFeeExceptions`.

Some significant changes have been made to the e2e tests to make them
compatible with this conditions.

`uatone` has also been put in a constant to avoid repetition (in
`app/params` package)

Relates to #44 

I realized that the running relayers would also have to update their
config to use PHOTON for the fees, or else all txs would be rejected. So
added a section to cover that part.

Also added a kind remind for validators that have `authz` transactions
submitted periodically (for example validators who support services like
restake) to update the tx fee denom as well.

Relates to #44

This PR adds a new message `MsgMintPhoton` inside a new `x/photon`
module.
List of changes:
- `x/photon` queries : `params` & `conversion_rate`
- `x/photon` transaction: `MsgMintPhoton`
- app plumbing with the new module
- Some relative changes were made to the e2e tests to remove anything
related to the `stake` denom (use `uatone` instead), which had some
impact on other tests that had to be fixed.
- Makefile:
- target `start-localnet-ci` use `uatone` denom instead of default
`stake`
- new target `mockgen` to generates the mocks from gov and photon
expected keepers
