summary
add inner bounds

tests

• unittests
• dockernet
  • verify bounds are set upon registration
  • verify hz halts if the inner bound is crossed

➜  stride git:(tight-bounds) ✗ stridedl q stakeibc show-host-zone GAIA

update bounds

$STRIDE_MAIN_CMD tx stakeibc set-redemption-rate-bounds GAIA 1 1.4 --from $STRIDE_ADMIN_ACCT -y | TRIM_TX

and query them

  max_inner_redemption_rate: "1.400000000000000000"
  max_redemption_rate: "1.500000000000000000"

try setting from the wrong account

$STRIDE_MAIN_CMD tx stakeibc set-redemption-rate-bounds GAIA 1.1 1.3 --from val1 -y | TRIM_TX

nit: it's a bit easier to read if you create these with MustNewDecFromStr

I don't think so cause I don't think validate basic is run when you call the msg server function directly
