This PR clarifies semantic conventions for HTTP retries and redirects and defines a span structure and linking as well as span attributes for retries. Changes were discussed recently at Instrumentation SIG meetings.
This change addresses a scenario which is in the scope for bringing the existing HTTP semantic conventions for tracing to an initial stable state, see related [otep #174](https://github.com/open-telemetry/oteps/pull/174).
* Prohibit usage of retired names in semantic conventions
This change adds a prohibition clause that requires that no old
metric or attribute name is used for a new attribute.
This is important to ensure reversibility of schema transformation
(converting from a new version to an old version of schema).
Without this restriction the following is possible:
Schema version 1. Attribute A exists.
Schema version 2. Attribute A is renamed to B. Appropriate schema file is created.
Schema version 3. Attribute A is introduced (a completely different new attribute).
Now attempting to go from Version 3 to version 1 is impossible since it requires
renaming B to A (for the change in version 2), but a different attribute A already exists.
* Fix based on comments
* Add changelog entry

Add a missing `</a>` closing tag for the `<a name="nettransport-attribute">` element. Without the closing tag, then entire page after that is taken as content of the anchor, which isn't correct and it breaks table formatting on the website.
Fixes#1760
## Changes
Removes `db.cassandra.keyspace` and `db.hbase.namespace` (in preference for using `db.name`).
Clarifies `db.name` in the case where a database product provides multiple concepts that could be mapped to `db.name`.
* Avoid using gRPC when generic RPC systems have same properties
The concept of "streaming" is supported by multiple protocols including gRPC, but also others.
