* chore: cleanup OpenTelemetry example
* chore: gofmt all code
* Refactor TestParseURL
This is in preparation for supporting query parameters
in ParseURL:
- use an expected *Options instance to execute assertions on
- extract assertions into helper function
- enable parallel testing
- condense test table
* Add query parameter parsing to ParseURL()
Before this change, ParseURL would only accept a very restricted
set of URLs (it returned an error, if it encountered any parameter).
This commit introduces the ability to process URLs like
redis://localhost/1?dial_timeout=10s
and similar.
Go programs which were providing a configuration tunable (e.g.
CLI flag, config entry or environment variable) to configure
the Redis connection now don't need to perform this task
themselves.

* Fix Redis Cluster issue during roll outs of new nodes with same addr (#1914)
* fix: recycle connections in some Redis Cluster scenarios
This issue was surfaced in a Cloud Provider solution that used for
rolling out new nodes using the same address (hostname) of the nodes
that will be replaced in a Redis Cluster, while the former ones once
depromoted as Slaves would continue in service during some mintues
for redirecting traffic.
The solution basically identifies when the connection could be stale
since a MOVED response will be returned using the same address (hostname)
that is being used by the connection. At that moment we consider the
connection as no longer usable forcing to recycle the connection.

* chore: cleanup OpenTelemetry example
* chore: gofmt all code
* Refactor TestParseURL
This is in preparation for supporting query parameters
in ParseURL:
- use an expected *Options instance to execute assertions on
- extract assertions into helper function
- enable parallel testing
- condense test table
* Add query parameter parsing to ParseURL()
Before this change, ParseURL would only accept a very restricted
set of URLs (it returned an error, if it encountered any parameter).
This commit introduces the ability to process URLs like
redis://localhost/1?dial_timeout=10s
and similar.
Go programs which were providing a configuration tunable (e.g.
CLI flag, config entry or environment variable) to configure
the Redis connection now don't need to perform this task
themselves.

* Fix Redis Cluster issue during roll outs of new nodes with same addr (#1914)
* fix: recycle connections in some Redis Cluster scenarios
This issue was surfaced in a Cloud Provider solution that used for
rolling out new nodes using the same address (hostname) of the nodes
that will be replaced in a Redis Cluster, while the former ones once
depromoted as Slaves would continue in service during some mintues
for redirecting traffic.
The solution basically identifies when the connection could be stale
since a MOVED response will be returned using the same address (hostname)
that is being used by the connection. At that moment we consider the
connection as no longer usable forcing to recycle the connection.

According to the opentelemetry specification this should always be set to client for database client

I've also removed the SetAttributes call and instead set the attributes during creation of the span.
This is what the library SHOULD be doing according to the opentelemetry api specification.
