fix(gitaly): disk_space saturation nfs-file9[0-2]

What

Drain the following storages temporarily:

• nfs-file90
• nfs-file91
• nfs-file92

Why

In https://thanos.gitlab.net/graph?g0.expr=max%20by(environment%2C%20tier%2C%20type%2C%20stage%2C%20shard%2C%20fqdn%2C%20device)%20(%0A%20%20clamp_min(%0A%20%20%20%20clamp_max(%0A%20%20%20%20%20%20(%0A%20%20%20%20%20%20%20%201%20-%20node_filesystem_avail_bytes%7Bfstype%3D~%22ext.%7Cxfs%22%2C%20environment%3D%22gprd%22%2Cstage%3D%22main%22%2Ctype%3D%22gitaly%22%7D%20%2F%20node_filesystem_size_bytes%7Bfstype%3D~%22ext.%7Cxfs%22%2C%20environment%3D%22gprd%22%2Cstage%3D%22main%22%2Ctype%3D%22gitaly%22%7D%0A%20%20%20%20%20%20)%0A%20%20%20%20%20%20%2C%0A%20%20%20%20%20%201)%0A%20%20%2C%0A%20%200)%0A)%20%3E%200.88%0A&g0.tab=0&g0.stacked=0&g0.range_input=1h&g0.max_source_resolution=0s&g0.deduplicate=1&g0.partial_response=0&g0.store_matches=%5B%5D we see that these servers are above 90% disk space utilization. This was caused by gitlab-com/gl-infra/production#17004 (closed).

We need to temporarily drain these storages until we are down to 80% disk_space then we can continue with our normal migration in https://gitlab.com/gitlab-com/gl-infra/production/-/issues/17002 after this is solved.
