[charts/gateway-otk] Escape JdbcUrl parameters in bundle file

[jmmAVGO]

This PR ensures that arguments passed as part of the JDBC connectiioin string are properly escaped when inserted into bunndle files. For example, jdbc-connection-oauth.bundle should read:

<l7:JdbcUrl>jdbc:mysql://dbserver:3306/test_1otk1_otk_db?useSSL=true&amp;requireSSL=true&amp;verifyServerCertificate=false</l7:JdbcUrl>

iinsntead of:

<l7:JdbcUrl>jdbc:mysql://dbserver:3306/test_1otk1_otk_db?useSSL=true&requireSSL=true&verifyServerCertificate=false</l7:JdbcUrl>

Benefits

This will allow OTK installatioins that use SSL to succeed

Drawbacks

Not a drawback, per se, but I wonder if this is complete? I don't know a lot about bundle files - are there other thingns that need to be escaped? Also, I assume I should open another PR against 'stable' after this?

@APIM-KiranVaddadi Scott iis asking iif you can review this problem; it may exist elsewhere, including the new method of installing otk inside the gateway helm chart

[jmmAVGO]

This chart is new deprecated. The change needs to be done here https://github.com/CAAPIM/apim-charts/blob/stable/charts/gateway/templates/otk-install-job.yaml#L54

@APIM-KiranVaddadi That may very well be, but releng is still using this chart, and we need it until we don't. Do you want to make the PR for the stable / gateway chart?

@Gazza7205 @APIM-KiranVaddadi , just to be clear, we're applying this fix for our internal pipeline. we're leaving fixing the gateway chart to you.
