Add new URLs for APIs ported from extensions

After port of extensions to core API we need to rename their URLs.

So, rename URLs and bump microversion for it.
Make new URLs work only with new microversion(s) 2.7+
and old with old microversions 1.0-2.6.
Add separate API router for v2 API as now we should split v1 and v2
logic.
Also, move updated APIs under v2 directory that will be used by both
API routers - v1 and v2.

List of updated collections is following:
 - os-availability-zone -> availability-zones
 - os-services -> services
 - os-quota-sets -> quota-sets
 - os-quota-class-sets -> quota-class-sets
 - os-share-manage -> shares/manage
 - os-share-unmanage -> shares/%s/action

List of updated member actions is following:
 - os-share-unmanage/%(share_id)s/unmanage -> shares/%(share_id)s/action
 - types/%(id)s/os-share-type-access -> types/%(id)s/share_type_access

List of updated action names is following:
 - os-access_allow -> access_allow
 - os-access_deny -> access_deny
 - os-access_list -> access_list
 - os-reset_status -> reset_status
 - os-force_delete -> force_delete
 - os-migrate_share -> migrate_share
 - os-extend -> extend
 - os-shrink -> shrink

List of updated attribute names is following:
 - os-share-type-access -> share-type-access

Partially implements bp ext-to-core
