Implement new features: Increase unbonding for people who choose 1 or 7 days of unbonding period

[Antropocosmist]

Some users choose 1 or 7 days unbonding period, but after they understand that they want to switch on 14 days of unbonding period.
For now, users need to unbond their LPs, wait for 1 or 7 days, and only after send their LPs to liquidity mining with 14 days of unbonding period.

It will be very helpful for users for users to have a button "Increase unbonding period" without waiting of 1 or 7 days.
As example to explain:
User send LPs to liquidity mining and choose 1 or 7 days period.
After user understand that better to choose 14 days.
User click on button "Increase Unbonding Period" and have a possibility to resend LPs to 14 days unbonding period without losing of 1 or 7 days.
Also, if user choose 1 day - user can resend LPs to 7 or 14 days of unbonding.
If user choose 7 days - user can resend LPs only to 14 days of unbonding.

It will good as for users, as for liquidity at Osmosis.

I don't know, is it only question of fron-end, and do we need to change something in back-end?
Do I need to create the same issue in back-end repo?

Also, idea what to do with reduction of unbonding period!

Will be very helpful to reduce unbonding time from 14 to 7 days.
And from 7 to 1 day.

Example:
User send LPs with 14 days of unbonding.
User understand that want to choose 7 days.
For now, user need to start unbonding and wait for 14 days to swith on 7 days.

Will be very helpful to create button "reduce unbonding period".
User can click on button and choose "7 days unbonding".
After it, user's LPs are sending to "7 days of unbonding", and user need to wait for 7 days, while LP's will be at 7 days of unbonding duration. All this 7 days, user will get reward as for 7 days of unbonding, not as for 14 days of unbonding.

The same for users who want to change unbonding time from 7 to 1 days. Just in this case, user need to wait for 6 days of transferring LPs from 7 days to 1 day of unbonding, and all 6 days user will get reward as for 1 day of unbonding, not as for 7 days of unbonding.

It will be the same like unbond LPs now, but in this case LPs will not be unbond totally, just will change "unbonding duration"
