[ASTERIXDB-2115] Add Component Ids to LSM Indexes

- user model changes: no

- storage format changes: no

- interface changes: yes

Details:

- Add LSMComponentId to all LSM components. Component Ids are managed

through IO operation callbacks.

- For memory component, it's ID is reset every time it's recycled.

- For disk component, it's ID is copied from the source component(s)

during flush/merge

- For indexes of a dataset, we need to guarantee all their memory

components should recieve the same ID. This is achieved using a shared

component Id generator.

- Fix memory component recycled callback, make sure it's called only

when we've indeed recycled the memory component
