add backward compatibility for createmeta_issuetypes & createmeta_fieldtypes

[paminov]

pr #1784 replaced createmeta_issuetypes & createmeta_fieldtypes with project_issue_types & project_issue_fields. This will break applications that use the library and utilize the createmeta_* methods.

thanks for this, could you add a deprecation warning to the functions before calling the replacement method.

@adehad thanks for pointing this out. I've added deprecation warnings to the methods.
