Remove Git circuit breaker 

Was introduced in the time that GitLab still used NFS, which is not
required anymore in most cases. By removing this, the API it calls will
return empty responses. This interface has to be removed in the next
major release, expected to be 12.0.

Beginning with GitLab 8.13.4, multiple paths can be chosen. New projects will be

## Handling failing repository storage
> [Introduced][ce-11449] in GitLab 9.5.
When GitLab detects access to the repositories storage fails repeatedly, it can
gracefully prevent attempts to access the storage. This might be useful when
the repositories are stored somewhere on the network.
This can be configured from the admin interface:
![circuitbreaker configuration](img/circuitbreaker_config.png)
**Number of access attempts**: The number of attempts GitLab will make to access a
storage when probing a shard.
**Number of failures before backing off**: The number of failures after which
GitLab will start temporarily disabling access to a storage shard on a host.
**Maximum git storage failures:** The number of failures of after which GitLab will
completely prevent access to the storage. The number of failures can be reset in
the admin interface: `https://gitlab.example.com/admin/health_check` or using the
[api](../api/repository_storage_health.md) to allow access to the storage again.
**Seconds to wait after a storage failure:** When access to a storage fails. GitLab
will prevent access to the storage for the time specified here. This allows the
filesystem to recover.
**Seconds before reseting failure information:** The time in seconds GitLab will
keep failure information. When no failures occur during this time, information about the
mount is reset.
**Seconds to wait for a storage access attempt:** The time in seconds GitLab will
try to access storage. After this time a timeout error will be raised.
To enable the circuitbreaker for repository storage you can flip the feature flag from a rails console:
```
Feature.enable('git_storage_circuit_breaker')
```
Alternatively it can be enabled by setting `true` in the `GIT_STORAGE_CIRCUIT_BREAKER` environment variable.
This approach would be used when enabling the circuit breaker on a single host.
When storage failures occur, this will be visible in the admin interface like this:
![failing storage](img/failing_storage.png)
To allow access to all storages, click the `Reset git storage health information` button.

The Circuitbreaker API is only accessible to administrators. All requests by
guests will respond with `401 Unauthorized`, and all requests by normal users
will respond with `403 Forbidden`.
## Repository Storages
### Get all storage information
Returns of all currently configured storages and their health information.
```
GET /circuit_breakers/repository_storage
```
```bash
curl --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" https://gitlab.example.com/api/v4/circuit_breakers/repository_storage

```json

},
{
"storage_name": "broken",
"failing_on_hosts": [
"web01", "worker01"
],
"total_failures": 1
}
]
```
### Get failing storages
This returns a list of all currently failing storages.
```
GET /circuit_breakers/repository_storage/failing
```
```bash
curl --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" https://gitlab.example.com/api/v4/circuit_breakers/repository_storage/failing

## Reset failing storage information
Use this remove all failing storage information and allow access to the storage again.
```
DELETE /circuit_breakers/repository_storage

```bash

Support of the circuit breaker is removed, as Gitaly can be configured to
to work without NFS and [communicate solely over HTTP](../administration/gitaly/index.md).
