'all_tenants' 'all_projects' query param is not only integer as mentioned in api-ref

[Ghanshyam Mann]

'all_tenants' and 'all_projects' are query param to list the resources for all tenants/projects.

Checking of this query param in code is different in different APIs.
- GET /servers API checks the value of 'all_tenants' as bool[1].
- other APIs just checks the present of it in req, like GET /os-server-groups, /os-fping

api-ref mentioned this param types as integer, boolean or string.

It is good to mention this query param type consistently to avoid confusion for users.

    Fix 'all_tenants' & 'all_projects' type in api-ref

    'all_tenants' and 'all_projects' are query param to
    list the resources for all tenants/projects.

    Checking of this query param in code is different in different APIs.
    - GET /servers and /servers/detail API checks the value of 'all_tenants'
      strictly as boolean if there is one present.
    - other APIs just checks the presence of it in req,
      like GET /os-server-groups, /os-fping

    api-ref mentioned this param types as integer, boolean or string.

    This commit make api-ref consistent to have type of this query param
    as string.
