Remove extra-specs from types-list command output
Remove extra-specs from types-list command output

type-list was including the extra-specs info in it's response,
however extra-specs are admin accessible only. As a result only admin
users could run type-list which is not what we want.

Add a seperate admin only call to provide volume-types with associated
extra-specs info (extra-specs-list).
