Setting default pg_num and pgp_num in the cephadm bootstrap_ceph config breaks the deploy in Quincy

[Victoria Martinez de la Cruz]

The configuration that we are using by default that sets pg_num and pgp_num values in bootstrap_ceph breaks devstack-plugin-ceph when using the latest Ceph version (quincy). The option "osd_pool_default_pg_autoscale_mode" is now on by default, colliding with the manual config for pg and pgps. We should use autoscale mode instead of configuring pg and pgp nums manually.

    Remove pg_num and pgp_num config from bootstrap_ceph

    The configuration that we are using by default that
    sets pg_num and pgp_num values in bootstrap_ceph
    breaks devstack-plugin-ceph when using the latest Ceph version (quincy).

    This patch sets removes the config for pg_num and pgp_num,
    so we delegate to Ceph the pools autoscaling.
