"task_state" field of a share is not shown via API

[Valeriy Ponomaryov]

After merge of commit [1] it is impossible to get via API value of "task_state" for any share.

The reason for it is that update of "view" part for API was marked as "experimental" and our core APIs "get" and "create" share do not satisfy this criterion. So, it is never attached to response.

    Fix experimental=True for view in microversion 2.5

    A previous patch added experimental=True to hide task_state field
    for any API call that would return share fields, such as "create"
    and "get" calls if different than microversion "2.5" with
    experimental=True. Turns out the field task_state should be
    returned always if microversion is "2.5" or above because it
    relates to a change in DB, not only to the usage of Share Migration
    feature. This patch fixes it by removing experimental=True
    dependency to show task_state field.
