[v1.1] Added etcd snapshot timeout parameter

[rawmind0]

Issue rancher/rancher#30663

Requires rancher/types#1196 : Timeout field has been added to Services.Etcd. BackupConfig. Once types PR is merged, this PR should be updated to use it.

Required by rancher/rancher#30885

This PR adds the feature to set etcd snapshot timeout instead of the default.

To limit the changes at the rke logic and functions parameters, the Services.Etcd. BackupConfig.Timeout field is read at cluster. SnapshotEtcd and cluster.RestoreEtcdSnapshot functions, using execution context to propagate the argument. docker.WaitForContainer function has been modified to set default WaitTimeout=300 or timeout provided by context value wait_timeout if provided
