server: stop after client disconnect (#7939)
* jobspec, api: add stop_after_client_disconnect

* nomad/state/state_store: error message typo

* structs: alloc methods to support stop_after_client_disconnect

1. a global AllocStates to track status changes with timestamps. We
   need this to track the time at which the alloc became lost
   originally.

2. ShouldClientStop() and WaitClientStop() to actually do the math

* scheduler/reconcile_util: delayByStopAfterClientDisconnect

* scheduler/reconcile: use delayByStopAfterClientDisconnect

* scheduler/util: updateNonTerminalAllocsToLost comments

This was setup to only update allocs to lost if the DesiredStatus had
already been set by the scheduler. It seems like the intention was to
update the status from any non-terminal state, and not all lost allocs
have been marked stop or evict by now

* scheduler/testing: AssertEvalStatus just use require

* scheduler/generic_sched: don't create a blocked eval if delayed

* scheduler/generic_sched_test: several scheduling cases

Lang Martin e100444740 csi: add mount_options to volumes and volume requests (#7398)
Add mount_options to both the volume definition on registration and to the volume block in the group where the volume is requested. If both are specified, the options provided in the request replace the options defined in the volume. They get passed to the NodePublishVolume, which causes the node plugin to actually mount the volume on the host.

Individual tasks just mount bind into the host mounted volume (unchanged behavior). An operator can mount the same volume with different options by specifying it twice in the group context.

quota: parse network stanza in quotas (#6511) 2019-10-24 10:41:54 -04:00

config: Hoist volume.config.source into volume
Currently, using a Volume in a job uses the following configuration:

```
volume "alias-name" {
  type = "volume-type"
  read_only = true

  config {
    source = "host_volume_name"
  }
}
```

This commit migrates to the following:

```
volume "alias-name" {
  type = "volume-type"
  source = "host_volume_name"
  read_only = true
}
```

The original design was based due to being uncertain about the future of storage
plugins, and to allow maxium flexibility.

However, this causes a few issues, namely:
- We frequently need to parse this configuration during submission,
scheduling, and mounting
- It complicates the configuration from and end users perspective
- It complicates the ability to do validation

As we understand the problem space of CSI a little more, it has become
clear that we won't need the `source` to be in config, as it will be
used in the majority of cases:

- Host Volumes: Always need a source
- Preallocated CSI Volumes: Always needs a source from a volume or claim name
- Dynamic Persistent CSI Volumes*: Always needs a source to attach the volumes
                                   to for managing upgrades and to avoid dangling.
- Dynamic Ephemeral CSI Volumes*: Less thought out, but `source` will probably point
                                  to the plugin name, and a `config` block will
                                  allow you to pass meta to the plugin. Or will
                                  point to a pre-configured ephemeral config.
*If implemented

The new design simplifies this by merging the source into the volume
stanza to solve the above issues with usability, performance, and error
handling.
