CAMEL-20763: camel-support Handle special characters in REST templates

[driseley]

Description

Ensure that any hypens or underscores in parameters in REST templates are removed before being parsed into a regular expression

The code will remove (using a regular expression match) any hyphens or underscores in REST template parameter names. This is required as the parameter name are parsed into regular expression named groups which support only letters and numbers as group names.

Target

• I checked that the commit is targeting the correct branch (note that Camel 3 uses camel-3.x, whereas Camel 4 uses the main branch)

Tracking

• If this is a large change, bug fix, or code improvement, I checked there is a JIRA issue filed for the change (usually before you start working on it).

https://issues.apache.org/jira/browse/CAMEL-20763

Apache Camel coding standards and style

• I checked that each commit in the pull request has a meaningful subject line and body.

• I have run mvn clean install -DskipTests locally and I have committed all auto-generated changes

If this is accepted could it also be backported to the 4.4.x LTS release? As this was introduced in 4.2.0 - it is not required on the 4.0.x LTS release

Apologies I thought I had run the tests, clearly I had not. That's fixed now and should pass
