bug: expired ibc-client on restart

[Anmol1696]

Overview

If there is a restart of the pods for whatever reason, it seems that the ibc client get expired fairly quickly.

Note: IBC client expiry is not limited to restarts of pods. So this needs to be solved more genrally as well.

Proposal

We should add a way to revie an IBC-client.
Initial thought is to have an /ibc/client-prop endpoint (we can have a better name), on the exposer itself. This can provide admin functions to submit a gov prop, pass it: for the ibc client

We can also just create an endpoint to be more specific to revive a

Alternatives

• Work with timeouts, to have a more reasonable setting. Expose this to the config, so this is user defined and specific
• Have traffic emulators running, that will keep performing txns on the chains to emulate ibc transations as well. This will make expriy of clients more rare.
