refactor: rename "server_configurations" => "configs" #3330

Problem:
The name `server_configurations` is extremely verbose and irritatingly
formal and dogmatic. This overlong name is a constant nuisance when
reading, writing, and coding.

It's also not even correct: these configurations are just as much
"client" configurations as they are "server" configurations.

Solution:
- Rename to a shorter name.
- Leave placeholder files for any old URLs that link to the old
  location.

+An Azure Pipelines language server
+
+`azure-pipelines-ls` can be installed via `npm`:
+
+```sh
+npm install -g azure-pipelines-language-server
+```
+
+By default `azure-pipelines-ls` will only work in files named `azure-pipelines.yml`, this can be changed by providing additional settings like so:
+```lua
+require("lspconfig").azure_pipelines_ls.setup {
+  ... -- other configuration for setup {}
+  settings = {
+      yaml = {
+          schemas = {
+              ["https://raw.githubusercontent.com/microsoft/azure-pipelines-vscode/master/service-schema.json"] = {
+                  "/azure-pipeline*.y*l",
+                  "/*.azure*",
+                  "Azure-Pipelines/**/*.y*l",
+                  "Pipelines/*.y*l",
+              },
+          },
+      },
+  },
+}
+```
+The Azure Pipelines LSP is a fork of `yaml-language-server` and as such the same settings can be passed to it as `yaml-language-server`.
