    Revert "Add reserved stores to the sample config file"
    
    This patch introduced double registering of the same
    config option groups which fails glance-api start
    if reserved stores are actually defined.
    
    The code utilizing these config options has not been
    merged which prevented testing to catch this.
    
    Closes-Bug: #1844108
    
    This reverts commit 4265e61bc84ce9bd085a95d8734647f4875af740.

Title:
  glance-api fails to start with duplicate option:
  filesystem_store_datadir error

Status in Glance:
  Fix Released

Bug description:
  NOTE:
  This bug is reproducible only after applying patch 'https://review.opendev.org/#/c/611253'

  Since commit 4265e61bc84ce9bd085a95d8734647f4875af740 [0] is merged, glance-api service fails to start with ERROR: duplicate option: filesystem_store_datadir.
  The reason for failure is glance_store [1] already registering the options for reserved stores. The above commit was aimed to add reserved stores options in sample config file, but it is also registering the same while doing so. Because of this failure the functional job is also timing out and failing on patch [2].

  In order to resolve this issue we should remove the part of
  registering the reserved store options logic from
  glance/common/config.py file, so that it can be only used when
  generating the sample config file.
