Create a new errata type 'other', which should be a catch-all for viewing errata which are not of the type 'bugfix', 'enhancement', or 'security'.

These features originate from this issue/bug: https://issues.redhat.com/browse/SAT-24725

This feature was initially opened as a bug fix. Original issue follows:

Description of problem:

When creating an include filter with date range "unspecified date TO specific date", the errata count is correct but the package count is showing fewer than the actual count.

Steps to Reproduce:

1. Current status of the CV:

32991 Packages
4993 Errata ( 1101 3248 644 )

2. Create filter as follows:

Type: Include Errata

Start Date: Unspecified

End date: Today(Jan 13,2023)

Date Type: 'Updated on or Issued on'

3. Publish a new version.

4. Status after adding the filter and publishing a new version:

28360 Packages
4993 Errata ( 1101 3248 644 )

Actual results:

Fewer package count with include filter.

Expected results:

Package count should not be altered as not specifying the start date and end date selected is today.
