TS-4099: missing proxy.process.http.transaction_counts.errors.errors
proxy.process.http.transaction_counts.errors.errors doesn't exist,
so replace it with proxy.process.http.transaction_counts.errors.other
where applicable.
> replace XML statistics with Lua
> -------------------------------

> Key: TS-4099
> URL: https://issues.apache.org/jira/browse/TS-4099
> Project: Traffic Server
> Issue Type: New Feature
> Components: Lua, Manager, Metrics
> Reporter: James Peach
> Assignee: James Peach
> Fix For: 6.2.0
>
>
> The custom metrics XML format is undocumented and difficult to use and
> extend. Since we plan to use Lua for configuration programmability, lets make
> a start by replacing this subsystem with Lua.
> It turns out that Lua is mostly more readable and easier to understand.
> Performance is roughly similar.
> Example syntax:
> {code}
> float 'proxy.node.user_agent_total_bytes_avg_10s' [[
> local self = ...
> return interval_delta_of_10s(self, function()
> return proxy.node.user_agent_total_bytes
> end)
> ]]
> counter 'proxy.node.origin_server_total_bytes' [[
> return proxy.node.http.origin_server_total_request_bytes +
> proxy.node.http.origin_server_total_response_bytes +
> proxy.node.http.parent_proxy_total_request_bytes +
> proxy.node.http.parent_proxy_total_response_bytes
> ]]
> {code}
