The share size can be limited by share type

In some usage scenarios, we do not want users to create too large share size, then affect the number of shares that can be created, mybe limited by project quota or backend storage.
or in some usage scenarios, creating a share that is too small makes no sense.

So we would better gives administrators the ability to set the maximum and minimum sizes for a single share by set share type extra_specs. then the size restrictions will be checked at the API level as part of share creation, extend, shrink or migration.
for example:
two new share type keys are supported for setting the minimum share size and maximum share size for that type.
'min_share_size'
'max_share_size'
