azuremonitorexporter: remove usage of LogRecord.Name field

[tigrannajaryan]

LogRecord.Name field is obsolete in this repo and will be deleted soon (already deleted from OTLP).

The field is currently used by azuremonitorexporter.

Please eliminate all references to LogRecord Name()/SetName() in azuremonitorexporter. The field is obsolete and there is no replacement for it.

@pcwiese as a codeowner of azuremonitorexporter can you help with this?

[bogdandrutu]

@reyang can you find an owner for the azuremonitorexporter?

[pcwiese]

I can take it, been busy with other stuff. This exporter isn't directly supported by MSFT

[tigrannajaryan]

Thanks @pcwiese, please do. I will assign this issue to you.

@eedorenko
Is this something you can take a look at given that you added support for logs? I'm not familiar with the properties you are setting on the envelope for logs/traces. Can this be removed entirely?

[tigrannajaryan]

@pcwiese @eedorenko will you be able to have a look at this? This is blocking a change that we need to make in the codebase. The LogRecord Name will be deleted and we can't until it is no longer referenced from anywhere.

I just commented out the use of it. I'm not sure what the replacement, if any, should be but it should not block forward progress in this repo.
