Cannot create multi-attached volumes when using eqlx

[wuyuting]

An Eqal volume can be attached to multi instances, however, this feature is not declared in eqal driver. As a result, if user create a multi-attached volumes when using eqal backend, they will be failed.

We need to declare multiattach is True in eqal driver.

I saw you reported quite a lot of bugs against a lot of cinder drivers. Have you ever actually tried multiattach on those drivers and 100% sure they can do multi-attach?
