This commit introduces:
- class ProxyProtocolInfo() , that:
  - performs parsing
  - validates subnet
  - run automated tests in DEBUG build
- variable mysql-proxy_protocol_networks . Accepted values:
  - empty string: disables PROXY protocol
  - '*' : allows connections from any IP
  - comma separated list of subnets
- automated testing in DEBUG build during start
- export of PROXY protocol information in internal session, using PROXY_V1
- a TAP test to verify various connections
bump version to 2.7.0 at the beginning of the development cycle
Implementation of PROXY protocol V1
bump version to 2.7.1 at the beginning of the development cycle
* If a MySQL connection fails or times out for a specific hostname, the
corresponding DNS record will be removed from DNS Cache. This ensures that outdated DNS
records are not retained. (Rest of the DNS resolution process remains unchanged)
* DNS cache functionality will automatically be disabled when ProxySQL is
run with the -M or --no-monitor option.

Move setting of compression level to correct place in the tap test (v2.7)
Fix leak of `SSL` caches for auxiliary threads
Fix compilation for GCC 4.8.5, compiler is not being able to either
handle reference initialization using brace-enclosed initializer lists.
SQLite amalgamation doesn't support DELETE with ORDER BY .
Thus the DELETE with ORDER BY was replaced by a SELECT to retrieve the maximum id,
followed by a DELETE up to that id.
bump version to 2.7.3 at the beginning of the development cycle
Incorrectly attempt to use a collation with id larger than 255 during backend handshake

Problem:
When creating a backend connection, if the frontend connection has configured a collation with id larger than 255 (for example using SET NAMES utf8mb4 COLLATE utf8mb4_0900_as_ci; , ProxySQL may try to create a new connection using such collation.
The problem is that at protocol level, during handshake only 1 byte can be used to configure the collation.
That means that if ProxySQL sets a collation greater than 255 , only the less significant byte is used.
Therefore even if ProxySQL believes that the backend connection will use the specified collation, mysql_real_connect() is using a different collation. For example, using collation 305 will lead to use collation 49 (305-256).

Solution:
When a collation id greater than 255 is detected, the default collation for that character set is used.
ProxySQL will later issue a SET NAMES ... COLLATE to address the mismatch.
Adding variable session_track_system_variables to `ignore_vars`

Also added `@@session.` and `@@global.` in the parser for SET statements (parse1v2)

See issue #4839
This new set of tests aims to check consistency between metrics exposed
by both, the Admin interface and the Prometheus exporter.
Ignore tracking of session_track_system_variables
Dynamic Prometheus gauge metrics are only exposed while the source for
the data used for the time-series exists. If the source of the data is
no longer present, we omit the metric in the exporter output.
Add PMM compatible 'runtime_mysql_servers_*' metrics to Prometheus exporter
