Field Name Normalization

The names of performance counters may contain characters which are invalid for field names on some backends. Valid field name characters are letters, numbers and underscore ([a-zA-Z0-9_]). Field names must begin with a letter.

uberAgent normalizes all field names as follows:

1. Replace invalid characters with an underscore.
2. Check if the field name starts with a letter. If not, prepend the name with uA_.
3. Remove consecutive underscore characters.

This is done for every type of receiver to make sure that field names are identical in every backend.

Note: this also applies to field names sent via custom scripts.

For instance:

Original input field: \Process(explorer)\Handle Count
After replacement:    uA_Process_explorer_Handle_Count
